Python Libraries :
Python is a powerful and versatile programming language widely used in software development , data science , web development , and more . One of the key reasons for its popularity is its extensive collection of Python libraries that simplify complex tasks . These libraries enable developers to work efficiently by providing reusable library routines and pre-written modules for various functionalities . Whether you are a beginner or an experienced Python programmer , understanding essential Python libraries can significantly enhance your coding efficiency .
What Are Python Libraries ?
Python is a structured programming language that emphasizes readability and efficiency . It is an interpreted language , meaning it executes code line by line . Python is highly favored due to its object-oriented programming features , extensive libraries, and support for various frameworks like Django .
Python Fundamentals
A Python library is a collection of Python code , modules , and packages that provide specific functionality . These libraries can be easily imported into a project , saving developers the time and effort required to write code from scratch . The Python Package Index ( PyPI ) is a popular repository where developers can find and install various open-source Python packages .
Categories of Python Libraries
1. Standard Library
Python comes with a built-in standard library that provides various functionalities , including file handling , data manipulation , and network communication. Some commonly used libraries from the standard library include :
- os – Interacting with the operating system.
- sys – System-specific parameters and functions.
- json – Working with JSON data.
- re – Regular expressions.
- math – Mathematical functions.
2. Data Science Libraries
For those interested in Data science course in Lucknow , Python offers numerous data science libraries :
