Python Standard Library

Python’s Standard Library is a treasure trove of pre-built modules that cater to a wide range of applications, from file handling and system operations to data manipulation and networking. These modules eliminate the need for reinventing the wheel and enable you to focus on solving specific problems efficiently.

os Module: The os module provides a platform-independent interface to interact with the operating system. It enables tasks like file and directory manipulation, environment variable access, and more.
python

# Example: Get the current working directory
current_directory = os.getcwd()
print(current_directory)
sys Module: The sys module provides access to Python’s runtime environment. It allows you to interact with system-specific parameters, like command-line arguments and Python version information.

import sys

# Example: Get command-line arguments
arguments = sys.argv
print(arguments)
datetime Module: The datetime module allows you to work with dates and times. It offers classes and methods to create, manipulate, and format dates and time values.

import datetime

# Example: Get the current date and time
current_time = datetime.datetime.now()
print(current_time)
math Module: The math module provides mathematical functions and constants to perform various numerical computations.

import math

# Example: Calculate the square root of a number
number = 25
square_root = math.sqrt(number)
print(square_root)
