In Python, the if-else statement is used to perform different actions based on a certain condition. It allows you to execute a block of code if a condition is true, and another block of code if the condition is false.
The general syntax of the if-else statement in Python is as follows:
In Python, a list is a built-in data structure that allows you to store a collection of items. It is an ordered and mutable (changeable) sequence. Each item in a list is called an element and can be of any data type, including numbers, strings, or even other lists. Lists are created using square brackets [ ] and commas , to separate the elements.
Here's an example that demonstrates various operations with lists:

In Python, operators are special symbols or characters that are used to perform operations on variables, values, or expressions. Python provides a wide range of operators that serve different purposes. Here are the main categories of operators in Python:
Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication, division, modulus, and exponentiation.
Addition: '+'
Subtraction: '-'
Multiplication: '*'
Division: '/'
Modulus (remainder): '%'
Exponentiation: '**'
Floor Division (quotient): '//'
In Python, a variable is a container that stores a value, which can be a number, a string, a boolean, lists, tuples, dictionaries or any other data type. You can assign a value to a variable using the equal sign (=).
For example:
x = "Hello, World!"
In this example, x is the name of the variable, and "Hello, World!" is the value that it stores.
