Functions allow programmers to organize code into reusable blocks. There are built-in functions and user-defined functions. Functions make code easier to develop, test and reuse. Variables inside functions can be local, global or nonlocal. Parameters pass data into functions, while functions can return values. Libraries contain pre-defined functions for tasks like mathematics and string manipulation.
This document discusses values, data types, and the five standard data types in Python. It defines that values are the fundamental things like numbers and strings that programs manipulate. Data type refers to the type and size of data that variables can hold. The five main data types in Python are numbers, strings, lists, tuples, and dictionaries. Numbers include integers, floating point values, and complex numbers. Lists and tuples are ordered sequences that can hold heterogeneous data, but lists are mutable while tuples are immutable. Strings are ordered sequences of characters. Dictionaries are unordered collections of key-value pairs.
This document discusses different types of flow control in Python programs. It explains that a program's control flow defines the order of execution and can be altered using control flow statements. There are three main types of control flow: sequential, conditional/selection, and iterative/looping.
Sequential flow executes code lines in order. Conditional/selection statements like if/else allow decisions based on conditions. Iterative/looping statements like for and while loops repeat code for a set number of iterations or as long as a condition is true. Specific conditional statements, loops, and examples are described in more detail.
The document discusses different types of conditional and control statements in Python including if, if-else, elif, nested if-else, while, for loops, and else with loops.
It provides the syntax and examples of each statement type. The if statement and if-else statement are used for simple decision making. The elif statement allows for chained conditional execution with more than two possibilities. Nested if-else allows if/elif/else statements within other conditionals. While and for loops are used to repeatedly execute blocks of code, with while looping until a condition is false and for looping over sequences. The else statement with loops executes code when the loop condition is false.
Python modules allow code reuse and organization. A module is a Python file with a .py extension that contains functions and other objects. Modules can be imported and their contents accessed using dot notation. Modules have a __name__ variable that is set to the module name when imported but is set to "__main__" when the file is executed as a script. Packages are collections of modules organized into directories, with each directory being a package. The Python path defines locations where modules can be found during imports.
Python is a versatile, object-oriented programming language that can be used for web development, data analysis, and more. It has a simple syntax and is easy to read and learn. Key features include being interpreted, dynamically typed, supporting functional and object-oriented programming. Common data types include numbers, strings, lists, dictionaries, tuples, and files. Functions and classes can be defined to organize and reuse code. Regular expressions provide powerful string manipulation. Python has a large standard library and is used widely in areas like GUIs, web scripting, AI, and scientific computing.
This document provides an agenda and overview for a Python tutorial presented over multiple sessions. The first session introduces Python and demonstrates how to use the Python interpreter. The second session covers basic Python data structures like lists, modules, input/output, and exceptions. An optional third session discusses unit testing. The document explains that Python is an easy to learn yet powerful programming language that supports object-oriented programming and high-level data structures in an interpreted, dynamic environment.

Provides an introductory level understanding of the Python Programming Language and language features. Serves as a guide for beginners and a reference to Python basics and language use cases.
This Edureka Python tutorial will help you in learning various sequences in Python - Lists, Tuples, Strings, Sets, Dictionaries. It will also explain various operations possible on them. Below are the topics covered in this tutorial:
1. Python Sequences
2. Python Lists
3. Python Tuples
4. Python Sets
5. Python Dictionaries
6. Python Strings
The document discusses Python data types. It describes the numeric data types integer, float, and complex which are used to represent numbers. Integer is a whole number without decimals, float has decimals, and complex numbers have real and imaginary parts. None is described as a null value. Strings are arrays of characters and can be indexed. Tuples and lists are ordered collections that can hold heterogeneous data types. Sets are unordered collections of unique items. Dictionaries are unordered collections of key-value pairs that allow accessing values via keys.
All data values in Python are encapsulated in relevant object classes. Everything in Python is an object and every object has an identity, a type, and a value. Like another object-oriented language such as Java or C++, there are several data types which are built into Python. Extension modules which are written in C, Java, or other languages can define additional types.
To determine a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable.
The document provides an introduction and overview of the Python programming language. It discusses that Python is an interpreted, object-oriented, high-level programming language that is easy to learn and read. It also covers Python features such as portability, extensive standard libraries, and support for functional, structured, and object-oriented programming. The document then discusses Python data types including numbers, strings, and various Python syntax elements before concluding with the history and evolution of the Python language through various versions.

This Edureka PPT on Tkinter tutorial covers all the basic aspects of creating and making use of your own simple Graphical User Interface (GUI) using Python. It establishes all of the concepts needed to get started with building your own user interfaces while coding in Python.
This document provides an introduction and overview of the Python programming language. It discusses what Python is, its features, applications, and how to install Python on Windows and Linux systems. It also covers Python basics like variables, data types, operators, comments, conditional statements like if/else, and loops like for, while, and nested loops. Examples are provided for key concepts. The document is intended as a beginner tutorial for learning Python.
Python is a dynamic, high-level, free open source, and interpreted programming language commonly used for developing websites and software, task automation, data analysis, and visualization. Control flow statements in Python include conditional statements like if/elif/else to make decisions, loops like for and while to repeat actions, and keywords like break, continue, and pass to control program flow. Exception handling uses try, except, and finally blocks to handle errors.
Break, Continue and Pass in Python.pdfNehaSpillai1
The break statement exits the current loop. The continue statement skips the current iteration and continues with the next. The pass statement acts as a placeholder and doesn't perform any operation - it allows empty functions or loops that will be implemented later.

Exception handling uses try, except, and finally blocks to handle errors.
Break, Continue and Pass in Python.pdfNehaSpillai1
The break statement exits the current loop. The continue statement skips the current iteration and continues with the next. The pass statement acts as a placeholder and doesn't perform any operation - it allows empty functions or loops that will be implemented later.
The document discusses various control flow statements in Python including conditional statements like if, if-else, if-elif-else, loop statements like while and for loops, and jump statements like break and continue. Indentation is used to declare blocks in Python instead of curly braces or parentheses. Conditional statements allow performing different computations depending on conditions. Loop statements repeat a block of code a specified number of times. Jump statements alter the flow of loops by skipping or terminating parts of a loop.
This document discusses for loops in Python and provides examples of using if statements, else clauses, and nested loops within for loops. It also discusses break and continue statements and how they can alter normal loop flow. Specifically, it shows that an else block after a for loop will execute if there is no break statement in the loop. It provides code examples of for loops with if/break statements and else blocks to illustrate when the else block does and does not execute. It also shows examples of nested for loops and using break/continue statements to terminate or skip iterations in a loop.
First in the series of slides for python programming, covering topics like programming language, python programming constructs, loops and control statements.
The document provides information on various decision making and looping constructs in Python like if, else, elif, for, while loops. It explains the syntax and usage of these statements with examples. Key decision making constructs covered include if-else, if-elif-else statements. Looping constructs covered include for loops over sequences, range function to generate sequences, while loops, break and continue keywords in loops. Nested if statements and usage of else block with for and while loops are also discussed.
While-For-loop in python used in collegessuser7a7cd61
This document discusses loops in Python programming. It covers for loops, range functions, break/continue/pass statements, booleans, while loops, and nested loops. Some key points:
- For loops iterate over sequences like lists and strings, while loops repeat code while a condition is true.
- Range functions generate numeric sequences for use in for loops. They can specify a start, end, and optional step size.
- Break/continue/pass are loop control statements - break exits the loop, continue skips to the next iteration.
- Boolean values are True or False and are used to check conditions in loops.
- Nested loops involve loops within other loops, like a for loop inside a for loop.
This document discusses decision making and loops in Python. It describes the different types of decision making statements like IF, IF-ELSE, and nested IF statements. It also explains while and for loops used to repeat a block of code. Additionally, it covers loop control statements such as break, continue, and pass that alter normal loop execution.
Conditional statements in Python like if, else, and elif direct the flow of execution based on evaluating conditions. Loops like for and while loops repeatedly execute code for a specified number of iterations or as long as a condition is true. Nested loops allow loops within loops, so an inner loop will repeat for each iteration of the outer enclosing loop. Patterns can be printed using for loops by iterating and printing values in nested loops.
Loops allow blocks of code to be executed repeatedly. The two main types of loops in Python are for loops and while loops. For loops are used to iterate over an iterable object like a list or string, while while loops continue executing until a condition is no longer true. Loop control statements like continue, break, and pass can change the normal execution flow of loops. Nested loops involve having a loop inside the body of another loop.
This document discusses decision making and loops in Python. It begins with an introduction to decision making using if/else statements and examples of checking conditions. It then covers different types of loops - for, while, and do-while loops. The for loop is used when the number of iterations is known, while the while loop is used when it is unknown. It provides examples of using range() with for loops and examples of while loops.
This document provides an overview of program control structures in C++ including conditional statements like if/else and switch statements as well as loops like for, while, and do-while. It explains the syntax and usage of each structure with examples. Key points covered include conditional branching, nested control structures, the break and continue keywords, whitespace and comments. The document emphasizes best practices for indentation and formatting source code for readability. It concludes with notes on maintaining a log book of programming work for grading purposes.
This document provides an introduction to server-side scripting and PHP. It discusses how server-side pages work by having the web server run scripts and send HTML to users' browsers. It then lists several common server-side scripting languages like PHP, ASP, and Python. The document proceeds to introduce PHP in more detail, covering its basics like syntax, variables, strings, arithmetic operators, and functions. It provides examples of conditional statements like if/else and looping with for and while loops.
The document discusses different types of control flow statements in Python including sequential, decision, and loop statements. Decision statements include if, if-else, and if-elif-else statements which allow conditional execution of code blocks based on boolean expressions. Loop statements like while and for loops allow repeating execution of code blocks. Nested conditional statements and multi-way decisions with if-elif-else are also covered.
This document discusses various computer arithmetic operations including addition, subtraction, multiplication, and division for signed magnitude and two's complement data representations. It describes the Booth multiplication algorithm, array multipliers for performing multiplication using combinational circuits, and the division algorithm. It also covers detecting divide overflow conditions.
The document provides an introduction to computer security including:
- The basic components of security such as confidentiality, integrity, and availability.
- Common security threats like snooping, modification, and denial of service attacks.
- Issues with security including operational challenges and human factors.
- An overview of security policies, access control models, and security models like Bell-LaPadula and Biba.
Cookies and sessions allow servers to remember information about users across multiple web pages. Cookies are small files stored on a user's computer that identify users and can store data to be accessed on subsequent page requests. Sessions use cookies to identify users and store temporary data on the server side to be accessed across multiple pages in one application, such as usernames or preferences. Both cookies and sessions must be started before any page output to ensure headers are sent before the page body.
This document discusses different aspects of functions in programming including declaring and calling functions, passing arguments to functions, and returning values from functions. It also covers variable scope. Some key points covered are declaring functions with and without arguments, specifying default values, returning single values or arrays from functions, and understanding variable scope and how it relates to the global and $GLOBALS keywords and array.
This document discusses various aspects of working with web forms in PHP, including:
1) Useful server variables for forms like QUERY_STRING and SERVER_NAME.
2) Accessing form parameters submitted to the server.
3) Processing forms with functions, including validating form data with techniques like checking for required fields and valid email addresses.
4) Displaying default values or error messages for form fields.
5) Stripping HTML tags from form inputs and encoding special characters for safe display.
The document provides examples of implementing each of these techniques.
The document discusses various programming concepts related to decision making and repetition in code including understanding true and false values, using if/elseif/else statements, equality and relational operators, logical operators, and using while and for loops to repeat code. Specific topics covered include evaluating booleans, making single and multi-line if statements, comparing different data types, negation, and printing select menus with loops.
This document discusses working with arrays in PHP. It covers array basics like creating and accessing arrays, looping through arrays with foreach and for loops, modifying arrays by adding/removing elements and sorting arrays. It also discusses multidimensional arrays, how to create them and access elements within them.
This document discusses text and numbers in programming. It covers defining and manipulating text strings using single or double quotes. Escape characters can be used inside strings. Text can be validated and formatted using various string functions like trim(), strlen(), strtoupper(), substr(), and str_replace(). Numbers can be integers or floats. Variables hold data and can be operated on with arithmetic and assignment operators like +, -, *, /, %, and .=. Variables can also be incremented, decremented, and placed inside strings.
This document provides an introduction and overview of PHP for beginners. It discusses PHP's use for building websites, how PHP code is run on web servers and accessed through browsers. It then highlights some key advantages of PHP like being free, cross-platform, and widely used. It demonstrates a basic "Hello World" PHP program and shows how to output HTML forms and formatted numbers. Finally, it outlines some basic rules of PHP programs regarding tags, syntax, whitespace, comments, and case sensitivity.
The document discusses capacity planning for a data warehouse environment. It notes that capacity planning is important given the large volumes of data and processing in a data warehouse. It describes factors that make capacity planning unique for a data warehouse, such as variable workloads and larger data volumes than operational systems. The document provides guidance on estimating disk storage needs, classifying and estimating processing workloads, creating workload profiles, identifying peak capacity needs, and selecting hardware capacity to meet needs.
Data warehousing involves assembling and managing data from various sources to provide an integrated view of enterprise information. A data warehouse contains consolidated, historical data used to support management decision making. It differs from operational databases by containing aggregated, non-volatile data optimized for queries rather than updates. The extract, transform, load (ETL) process migrates data from source systems to the warehouse, transforming it as needed. Process managers oversee loading, maintaining, and querying the warehouse data.
Search engines allow users to search the vast collection of documents on the web. They consist of crawlers that fetch web pages, indexers that analyze page content and links, and interfaces that allow users to enter queries. Crawlers add pages to an index by following links, and indexers create inverted indexes to map words to pages. When a query is searched, results are retrieved from the index and ranked based on relevance. PageRank is a key algorithm that ranks pages higher that receive more links from other highly ranked pages. While it effectively searches the large, diverse and dynamic web, search poses challenges in understanding ambiguous queries over an evolving collection.
Web mining involves applying data mining techniques to discover useful information from web data. There are three types of web mining: web content mining analyzes data within web pages, web structure mining examines the hyperlink structure between pages, and web usage mining involves analyzing server logs to discover patterns in user behavior and interactions with websites. Web mining has applications in website design, web traffic analysis, e-commerce personalization, and security/crime investigation.
Information privacy and data mining
The document discusses information privacy and data mining. It defines information privacy as an individual's ability to control how information about them is shared. It outlines the basic OECD principles for protecting information privacy, including collection limitation, purpose specification, use limitation, security safeguards, and accountability. It describes common uses of data mining like fraud prevention but also potential misuses that can violate privacy. The document also discusses the primary aims of data mining applications and five pitfalls like unintentional mistakes, intentional abuse, and mission creep.
The document discusses cluster analysis, which groups data objects into clusters so that objects within a cluster are similar but dissimilar to objects in other clusters. It describes key characteristics of clustering, including that it is unsupervised learning and the clusters are determined algorithmically rather than by humans. Various clustering algorithms are covered, including partitioning, hierarchical, density-based, and grid-based methods. Applications of clustering discussed include business intelligence, image recognition, web search, outlier detection, and biology. Requirements for effective clustering in data mining are also outlined.
Association analysis is a technique used to uncover relationships between items in transactional data. It involves finding frequent itemsets whose occurrence exceeds a minimum support threshold, and then generating association rules from these itemsets that satisfy minimum confidence. The Apriori algorithm is commonly used for this task, as it leverages the Apriori property to prune the search space - if an itemset is infrequent, its supersets cannot be frequent. It performs multiple database scans to iteratively grow frequent itemsets and extract high confidence rules.
Classification techniques in data miningKamal Acharya
The document discusses classification algorithms in machine learning. It provides an overview of various classification algorithms including decision tree classifiers, rule-based classifiers, nearest neighbor classifiers, Bayesian classifiers, and artificial neural network classifiers. It then describes the supervised learning process for classification, which involves using a training set to construct a classification model and then applying the model to a test set to classify new data. Finally, it provides a detailed example of how a decision tree classifier is constructed from a training dataset and how it can be used to classify data in the test set.
This document outlines a chapter on data preprocessing that discusses data types, attributes, and preprocessing tasks. It begins by defining data and attributes, then describes different types of attributes like nominal, binary, ordinal, and numeric attributes. It also discusses different types of datasets like records, documents, transactions, and graphs. The major section on data preprocessing outlines why it is important and describes tasks like data cleaning, integration, transformation, reduction, and discretization to prepare dirty or unstructured data for analysis.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

17. Python for Loop
• What is for loop in Python?
• Syntax of for Loop
• Flowchart of for loop
• Example: Python for Loop
• The range() function
• for loop with else
18. What is for loop in Python?
• Is used to iterate over a sequence (list, tuple, string) or other iterable
objects
• Iterating over a sequence is called traversal
19. • Syntax of for Loop:
• Here, val is the variable that takes the value of the item inside the
sequence on each iteration
• Loop continues until we reach the last item in the sequence. The body
of for loop is separated from the rest of the code using indentation.
23. The range() function
• Can generate a sequence of numbers using range() function
• range(10) will generate numbers from 0 to 9 (10 numbers)
• Can also define the start, stop and step size as
range(start,stop,stepsize)
• Step size defaults to 1 if not provided.
• Does not store all the values in memory, it would be inefficient
• So it remembers the start, stop, step size and generates the next
number on the go
27. Python while Loop
• What is while loop in Python?
• Syntax of while Loop in Python
• Flowchart of while loop
• Example: Python while Loop
• while loop with else
28. What is while loop in Python?
• Is used to iterate over a block of code as long as the test expression
(condition) is true
• Generally this loop is used when we don't know beforehand, the
number of times to iterate
29. Syntax of while Loop in Python
• Python interprets any non-zero value as True. None and 0 are
interpreted as False.
35. Python break and continue
• What is the use of break and continue in Python?
• Python break statement
• Syntax of break
• Flowchart of break
• Example of break
• Python continue statement
• Syntax of Continue
• Flowchart of continue
• Example: Python continue
36. What is the use of break and continue in
Python?
• break and continue statements can alter the flow of a normal loop
• Loops iterate over a block of code until test expression is false, but
sometimes we wish to terminate the current iteration or even the
whole loop without checking test expression
• break and continue statements are used in these cases
37. Python break statement
• Terminates the loop containing it
• Control of the program flows to the statement immediately after the
body of the loop.
• If break statement is inside a nested loop (loop inside another loop),
break will terminate the innermost loop
• Syntax of break
41. Python continue statement
• Is used to skip the rest of the code inside a loop for the current
iteration only
• Loop does not terminate but continues on with the next iteration
• Syntax of Continue
45. Python pass statement
• What is pass statement in Python?
• Syntax of pass
• Example: pass Statement
46. What is pass statement in Python?
• pass is a null statement
• The difference between a comment and pass statement in Python is
that, while the interpreter ignores a comment entirely, pass is not
ignored
• However, nothing happens when pass is executed
• It results into no operation (NOP)
• Syntax of pass
