This article explores Python modules and Python packages, two mechanisms that facilitate modular programming. Modular programming refers to the process of breaking a large, unwieldy programming task into separate, smaller, more manageable subtasks or modules.

A module is a file with the extension.py that contains Python or C executable code. A module is made up of a number of Python statements and expressions. Modules allow us to use pre-defined variables, functions, and classes. This cuts down on development time and allows code to be reused. The majority of modules are intended to tackle specific diff...
We can create a module by writing some code in a file and saving that file in a .py extension. Let us create a module named pythongeeks.py. Example of module in Python Output
We can import a module by using the import keyword Example of importing a module in Python Output We can import every object in a module by using the asterisk * operator. Example of importing a module in Python Output Likewise, we can import a specific function from a module. Example of importing a module in Python Output We can also alias a module...
Python has a built-in function called dir(). It accepts a module name as an input and returns a sorted list of all attributes and functions contained in the provided module. Example of dir() in Python Output
To import a module, Python first searches in the current directory. If the module doesn’t exist in the current directory, it then searches in all the directories present in the PYTHONPATH variable. If it still can’t find the directory, it then proceeds to the default directory. It raises a ModuleNotFoundError if it doesn’t find the module in any of...
To provide an application development environment, a python package establishes a hierarchical directory structure with several modules and sub-packages. They are nothing more than a bundle of modules and sub-packages.
To create a Python package, we need to create a directory with a __init__.py file and a module. Suppose we have created a package named website with the previously created module pythongeeks.py in it. We can import the website package by using the import keyword and a dot operator. Example of importing a package in Python Output Similar to modules,...
The following are some of the distinctions between Modules and Packages: 1. A Package is a directory containing numerous modules and sub-packages, whereas a Module is a.py file containing Python code. 2. An __init__ .py file is required to create a package. There is no such necessity when it comes to creating modules. 3. We can import all objects i...
The principle is the same for functions, modules, and packages. They want to make it as simple as possible for code to be reused. Their core idea is the same, despite the fact that they appear and operate differently. Multiple Python statements and expressions make up a function. Multiple Python functions make up a module and multiple Python module...
Q1. Write a program to import the math module and print the pi value. Ans 1. Complete code is as follows: Output Q2. Write a program to import all the objects in the random module and print a random integer between 20 and 30 (including). Ans 2. Complete code is as follows: Output Q3. Write a program to import the numpy package and print the log val...
Aug 23, 2023 · Learn how to structure Python code by creating modules, defining functions and classes, creating packages, importing modules, and more.
1 day ago · A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended. Within a module, the module’s name (as a string) is available as the value of the global variable __name__.
A Python module can have a set of functions, classes, or variables defined and implemented. The example above includes two files: mygame/game.py. mygame/draw.py. The Python script game.py implements the game.
Libraries. A library is a collection of modules and packages that you can install and use in your project. For example, the matplotlib library contains several packages and modules for...
