What are Libraries in Programming Language
                     WHAT ARE LIBRARIES IN 
PROGRAMMING LANGUAGE?
What is a library?
In programming, a definition 
of library can be following: a 
collection of pre-compiled 
and non-volatile routines 
used by programs. 
These routines, sometimes 
called modules, can include 
configuration data, 
documentation, message 
templates, subroutines, 
classes, values or type 
specifications.

Why Use Software 
Libraries?
Software libraries are 
collections of useful and 
common functions, data, 
(object) classes, values, or 
data types that you may use 
in the normal course of 
programming work.

How Do Libraries 
Work?
There are many ways a 
software library may exist. 
Python would add some code 
to bind the defined C 
functions to a variable to 
access those functions. 
Once complete, Python will 
need to know the location of 
this new library.

NumPy
Primary Language: Python
Use: NumPy is a library used 
to make powerful arrays. For 
machine learning, NumPy 
divides the data and 
manipulates it easily.

Matplotlib
Primary Language: Python
Use: Going off of the above, 
Matplotlib is used with 
NumPy to help with datasets. 
Specifically, Matplotlib 
handles large datasets and 
comes complete with 
standard graphing functions. 
It’s also useful for visualizing 
values over time.

TensorFlow
Primary Language: Python or 
C++
Use: TensorFlow is a library 
developed by Google to 
facilitate the creation and 
training of machine learning 
models and neural networks. 
It can be used to create and 
train machine learning 
models.

Keras
Primary Language: Python
Use: Keras is also a library 
developed to facilitate the 
creation and training of 
machine learning models and 
neural networks. But going 
off the above, Keras was 
introduced to simplify 
TensorFlow. This library can 
make machine learning 
significantly easier and it still 
uses TensorFlow as a 
backend.

Pillow
Primary Language: Python
Use: In Python, you can use 
the Pillow library to create 
bitmap images.

SFML
Primary Language: C++
Use: The Simple and Fast 
Multimedia Library (SFML) is 
a library that allows for the 
creation of images, 
generation of sound effects, 
and even connecting of 
multiple computers.

p5
Primary Language: JavaScript
Use: p5.js is one of the most 
well-known JavaScript 
libraries with tons of built-in 
code.
