What is the difference between library and module in Python?

Answer 1

Hi !

Module:
Simply put, a module in python is a .py file that defines one or more function/classes which you intend to reuse in different codes of your program.

To reuse the functions of a given module you simply need to import the module using:

import <modulename> # to import the entire module

from <modulename> import <classname> # imports a class from a module

As regards the module name, Python treats the file name as the module names.

By default, the name of the module is stored in the name space as a string type. The module name can be called within the module by calling the global variable __name__.

Library
Unlike C or C++, the term library does not have any specific contextual meaning in p\Python. When used in Python, a library is used loosely to describe a collection of the core modules.

The term ‘standard library‘ in Python language refers to the collection of exact syntax, token and semantics of the Python language which comes bundled with the core Python distribution.

In Python, the standard library is written in C language and it handles the standard functionalities like file I/O and other core modules that make Python what it is. The python standard library lists down more than 200 such core modules that form the core of Python.

“Additional libraries” refer to those optional components that are commonly included in Python distributions.

The Python installers for the Windows automatically adds the standard library and some additional libraries.

For Unix-like operating systems, the additional library is generally provided as a collection of packages. In Unix Os, one may have to use packaging tools like easyinstall or pip to use these additional libraries.

Types of Modules. A Module in Analytica is a collection of variables and other objects. ... Library: A Library is a type of Module that contains Functions and/or other objects available for use in multiple Models. Filed Library: A library saved in its own file.
Python library is a collection of functions and methods that allows you to perform lots of actions without writing your own code. For example, if you are working with data, numpy, scipy, pandas, etc. are the libraries you must know.
