Python is known for its simplicity, readability, and extensive set of libraries and frameworks. But did you know that it also has an impressive collection of built-in functions? These functions are part of the Python Standard Library, which provides a wide range of useful tools for everyday programming tasks. By learning these functions, you can save time, reduce redundancy, and improve your productivity as a developer.

In this guide, we will explore some of the most commonly used standard library functions in Python, along with practical code examples. We will cover topics such as data manipulation, file handling, error handling, and more. Let’s get started!

Data Manipulation

The math module contains various mathematical operations that can be performed on numbers. Here are some examples:

• Calculate the square root of a number using sqrt() function:

import math
number = 25
square_root = math.sqrt(number)
print("Square Root:", square_root)

• Find the absolute value of a number using fabs() function:
