Python Library | The Best Article on Python’s Various Libraries


1. Python Library

After Modules and Python Packages, we shift our discussion to Python Library. Let’s begin.

2. An Introduction to Libraries

We know that a module is a file with some Python code, and a package is a directory for subpackages and modules. But the line between a package and a Python library is quite blurred.

Python Libraries

Python Libraries

A Python library is a reusable chunk of code that you may want to include in your programs/ projects. Compared to languages like C++ or C, a Python library does not pertain to any specific context in Python. Here, a ‘library’ loosely describes a collection of core modules. Essentially, then, a library is a collection of modules. A package is a library that can be installed using a package manager like rubygems or npm.

3. The Python Standard Library

The Python standard Library is a collection of exact syntax, token, and semantics of Python. It comes bundled with core Python distribution. We mentioned this when we began with an introduction.

It is written in C, and handles functionality like I/O and other core modules. All this functionality together makes Python the language it is. More than 200 core modules sit at the heart of the standard library. This library ships with Python. But in addition to this library, you can also access a growing collection of several thousand components from the Python Package Index (PyPI). We mentioned it in the previous blog.

4. Important Python Libraries

Next, we will see twenty Python libraries list that will take you places in your journey with Python. These are also the Python libraries for Data Science.

a. Matplotlib

Matplotlib helps with data analyzing, and is a numerical plotting library. We talked about it in Python for Data Science.

b. Pandas

Like we’ve said before, Pandas is a must for data-science. It provides fast, expressive, and flexible data structures to easily (and intuitively) work with structured (tabular, multidimensional, potentially heterogeneous) and time-series data.

c. Requests

Requests is a Python Library that lets you send HTTP/1.1 requests, add headers, form data, multipart files, and parameters with simple Python dictionaries. It also lets you access the response data in the same way.

SQLAlchemy is a library with well-known enterprise-level patterns. It was designed for efficient and high-performing database-access.

f. BeautifulSoup

It may be a bit slow, BeautifulSoup has an excellent XML- and HTML- parsing library for beginners.

g. Pyglet

Pyglet is an excellent choice for an object-oriented programming interface in developing games. In fact, it also finds use in developing other visually-rich applications for Mac OS X, Windows, and Linux. In the 90s, when people were bored, they resorted to playing Minecraft on their computers. Pyglet is the engine behind Minecraft.
