Python libraries are collections of pre-written code that provide specific functionality, allowing developers to perform complex tasks without having to write code from scratch. They save time, enhance productivity, and reduce the likelihood of errors.

Types of Python Libraries
Standard Libraries
Bundled with Python installations, these libraries cover core functionalities like file I/O, math, and system operations. Examples:

math for mathematical functions

os for operating system interaction

datetime for date and time operations

Third-Party Libraries
Developed by the Python community and available via package managers like pip. Examples:

NumPy for numerical computations

Pandas for data manipulation

Requests for HTTP requests

Key Features of Python Libraries
Ease of Use: Simplify complex tasks by providing pre-built modules and functions.

Diversity: Cover a wide range of applications, from web development to machine learning.

Extensibility: Can be customized or extended for specific use cases.
