Basics

A list is a collection of values that can be of any data type (e.g. integers, strings, floats, etc.). Lists are ordered and mutable, meaning that you can add, remove, or change elements within the list. Lists are represented by square brackets [].For example: Some common operations for lists include: indexing, slicing, concatenating, checking the […]

Tuples are an ordered and immutable sequence of items, often used to store multiple items as a single unit. Tuples are defined by enclosing elements within parentheses ( ). Tuples can contain items of any type and can have duplicates. The items in a tuple can be accessed using indexing and slicing, just like lists.

Functions in Python are a way to organize and reuse code. A function is a block of code that takes input parameters, performs a set of operations, and returns an output (or multiple outputs). Functions can be called multiple times and from different parts of a program.Defining a function in Python starts with the def

Exception handling in Python allows a programmer to handle runtime errors by catching exceptions and taking appropriate action to handle them. In Python, exceptions are raised when an error occurs during execution of the program. An exception can be handled using a try statement, which allows the programmer to catch exceptions and take appropriate action.

Python provides different control flow statements to control the flow of execution in a program:if statement – Conditional execution of a block of code based on a certain condition.for loop – Iteration over a sequence of elements, such as a list, tuple or string.while loop – Continuously executing a block of code until a certain

The input() function in Python is used to take input from the user via the console. The input received is always in the form of a string, and you can process or convert it as needed. Syntax: input(prompt) Console Input Function in Python The input() function in Python is used to take input from the

Python has various data types to represent different types of values. Some of the most commonly used data types are:int (integers) – positive or negative whole numbers,e.g. 10, -20, 0 float (floating-point numbers) – numbers with decimal points,e.g. 1.0, 3.14, -0.5 complex (complex numbers) – numbers with real and imaginary parts,e.g. 1 + 2j, 3.2

Operators are symbols that perform specific operations on values (operands) and produce a result. There are several types of operators in Python, including:Arithmetic operators: perform arithmetic operations like addition, subtraction, multiplication, division and exponentiation.+(addition)-(subtraction)*(multiplication)/ (division)% (modulus)** (exponentiation) Comparison operators: compare two values and return a Boolean value indicating if the comparison is true or false.==

Identifiers in Python For example,The following are valid Python identifier names:myVariable_privateMY_CONSTANTsum_of_squares And the following are invalid Python identifier names:123abcifelseforwhile Python Keywords In Python, keywords are reserved words that have a special meaning and cannot be used as identifier names for variables, functions, classes, or any other objects.Here is a list of Python keywords:and, as, assert,

There are several Integrated Development Environments (IDEs) available for Python programming, here are steps to install some of the popular ones: IDLE (Python’s built-in IDE): Python comes with IDLE, a basic IDE that is included in the standard distribution.IDLE is available for Windows, macOS, and Linux, and can be installed by installing Python itself. https://www.python.org/downloads/
