Functions are blocks of reusable code in Python that perform a specific task. They take inputs, process them, and return outputs. Functions can be called from anywhere in your code, allowing you to avoid duplicating the same code in multiple places. Functions make code more modular, easier to read and maintain, and allow for better code organization.
Here is an example of a simple Python function that takes in two arguments and returns their sum:
Loops are a key programming construct in Python that allow you to execute a block of code repeatedly. The two most common types of loops are for loops and while loops. For loops are used to iterate over a sequence of values, such as a list, and execute a block of code for each value.
Python has a number of built-in data types that are used to represent different kinds of data. Here are some of the main data types in Python:
Integer: Integers are whole numbers, such as 1, 2, 3, -1, -2, -3, and 0. In Python, you can define an integer variable like this:
