If we need to import everything from a module and we don’t want to use the dot operator, do this: > from math import * Note that while importing from a module in this way, we don’t need to use the dot operator while calling the function or using the attribute. You can also import multiple attributes and functions from a module: > from math import pi, sqrt You can import a specific function, class, or attribute from a module rather than importing the entire module. To call the greeting function of mypymodule, we simply need to use the dot notation: Let’s import our user-defined module from the previous section into our Python shell: > import mypymodule We use the import keyword to import both built-in and user-defined modules in Python.

Half of our job is over, now let’s learn how to import these modules. Write this code in a file and save the file with the name mypymodule.py. To create a module, just put the code inside a. You can create your own functions and classes, put them inside modules and voila! You can now include hundreds of lines of code into any program just by writing a simple import statement. User-Defined Modules in PythonĪnother superpower of Python is that it lets you take things in your own hands. You can import and use any of the built-in modules whenever you like in your program. To name a few, Python contains modules like “os”, “sys”, “datetime”, “random”. Hence, it provides a lot of reusable code.
This rich standard library contains lots of built-in modules. One of the many superpowers of Python is that it comes with a “rich standard library”. A module may contain functions, classes, lists, etc.
A module is simply a “Python file” which contains code we can reuse in multiple Python programs.
Modules provide us with a way to share reusable functions. Keeping you updated with latest technology trends, Join TechVidvan on Telegram What are Python Modules?
