What's the Difference Between a Python Module and a Python Package

What's the difference between a Python module and a Python package?

A module is a single file (or files) that are imported under one import and used.
e.g.

import my_module

A package is a collection of modules in directories that give a package hierarchy.

from my_package.timing.danger.internets import function_of_love

Documentation for modules

Introduction to packages

Module vs. Package?

x may be a package or a module and y is something inside that module/package.

A module is a .py file, a package is a folder with an __init__.py file. When you import a package as a module, the contents of __init__.py module are imported.

Difference between library vs module vs package vs object in Python

1-object is instance of class

2-every file of Python source code whose name ends in a .py extension is a module

3-package is collection of modules. It is a directory which contains a special file __init__.py

4-Python packages without an __init__.py file are known as “namespace packages”

5-Library is collection of various packages

6-A framework is a large codebase, or collection of code, meant to provide universal, reusable behavior for a targeted project ,frameworks are different from other external codebases, such as libraries, because they feature inversion of control

Whats the difference between a module and a library in Python?

From The Python Tutorial - Modules

  • Module:

    A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended.

  • Package:

    Packages are a way of structuring Python’s module namespace by using “dotted module names”.

If you read the documentation for the import statement gives more details, for example:

Python has only one type of module object, and all modules are of this
type, regardless of whether the module is implemented in Python, C, or
something else. To help organize modules and provide a naming
hierarchy, Python has a concept of packages.

You can think of packages as the directories on a file system and
modules as files within directories, but don’t take this analogy too
literally since packages and modules need not originate from the file
system. For the purposes of this documentation, we’ll use this
convenient analogy of directories and files. Like file system
directories, packages are organized hierarchically, and packages may
themselves contain subpackages, as well as regular modules.

It’s important to keep in mind that all packages are modules, but not
all modules are packages. Or put another way, packages are just a
special kind of module. Specifically, any module that contains a
__path__ attribute is considered a package.

Hence the term module refers to a specific entity: it's a class whose instances are the module objects you use in python programs. It is also used, by analogy, to refer to the file in the file system from which these instances "are created".

The term script is used to refer to a module whose aim is to be executed. It has the same meaning as "program" or "application", but it is usually used to describe simple and small programs(i.e. a single file with at most some hundreds of lines). Writing a script takes minutes or few hours.

The term library is simply a generic term for a bunch of code that was designed with the aim of being usable by many applications. It provides some generic functionality that can be used by specific applications.

When a module/package/something else is "published" people often refer to it as a library. Often libraries contain a package or multiple related packages, but it could be even a single module.

Libraries usually do not provide any specific functionality, i.e. you cannot "run a library".

The API can have different meanings depending on the context. For example:

  • it can define a protocol like the DB API or the buffer protocol.
  • it can define how to interact with an application(e.g. the Python/C API)
  • when related to a library/package it simply the interface provided by that library for its functionality(set of functions/classes/constants etc.)

In any case an API is not python code. It's a description which may be more or less formal.

Python module vs sub-module vs package vs sub-package

package
|-- __init__.py
|-- module.py
|-- sub_package
|-- __init__.py
|-- sub_module.py

Consider packages and sub-packages as folders and sub-folders containing init.py file with other python files.

modules are the python files inside the package.

sub-modules are the python files inside the sub-package.

Difference between Module and Class in Python

  • Module:

    A module is a file containing Python definitions and statements.

As the doc say.

So a module in python is simply a way to organize the code, and it contains either python classes or just functions.
If you need those classes or functions in your project, you just import them.
For instance, the math module in python contains just a bunch of functions, and you just call those needed (math.sin).
Just have a look at this question.

On the other hand a python class is something similar to a java class, it's only structured in a slightly different way.

What is the difference between a module and a script in Python?

A script is generally a directly executable piece of code, run by itself. A module is generally a library, imported by other pieces of code.

Note that there's no internal distinction -- both are executable and importable, although library code often won't do anything (or will just run its unit tests) when executed directly and importing code designed to be a script will cause it to execute, hence the common if __name__ == "__main__" test.
