Python Standard Library

Python Standard library is a collection of modules and packages bundled with the Python language. It is quite extensive and includes numerous modules covering a wide range of functionalities. It has almost 200 modules, and the exact number of modules may vary depending on the Python version and updates.

Python’s standard library makes it easier for developers to accomplish various tasks without installing additional third-party packages. Some of the modules are as follows:

os
sys
math
random
datetime
socket
json
re

os

The os library provides a portable way to use operating system-dependent functionality, such as interacting with the file system, running shell commands, and accessing environment variables.

sys

The sys module provides access to some variables used or maintained by the Python interpreter and to functions that interact with the interpreter. It’s commonly used for system-specific parameters and functions.

math

The math module provides mathematical functions defined by the C standard. These include basic arithmetic operations, trigonometric functions, logarithmic functions, etc.

random

The random module implements pseudo-random number generators for various distributions. It’s commonly used for generating random numbers, shuffling sequences, and selecting random items.

datetime

The datetime supplies classes for manipulating dates and times. It’s useful for working with timestamps and time zones and performing date arithmetic.

socket

The socket module is widely used for network programming. It allows Python programs to establish network connections and communicate using various protocols.

json

The json module provides functions for encoding and decoding JSON data. JSON (JavaScript Object Notation) is a lightweight data exchange format for web applications.

re

The re module supports regular expressions, powerful tools for pattern matching and text manipulation.

logging

The logging module provides a flexible framework for emitting log messages from Python programs. It supports various logging levels, customizable formatting, and different output destinations.
