How to Create and Import Python Modules and Packages?

Writing Python Modules and Packages

Introducing Modules and Packages

In Python, a module is a file (.py) containing Python definitions and statements. The file name serves as the module name. A package, on the other hand, is a collection of modules grouped within a directory that contains an __init__.py file, which enables Python to recognize it as a package.

Creating a Module

To create a module, follow these steps:

1. Create a new file with a .py extension (e.g., hello.py).
2. Define functions or classes within the file (e.g., def helloworld():).
3. Save the file.

Importing a Module

To use a module, import it using the import statement:

import hello

Creating a Package

To create a package:

1. Create a new directory (e.g., HelloModule).
2. Create an __init__.py file within the directory.
3. Include additional .py files with your modules in the directory (e.g., hellomodule.py).

Importing a Package

Importing a package is similar to importing a module:

import HelloModule

Conclusion

Following these steps, you can create Python modules and packages that can be easily imported and reused. For further details, refer to the documentation on Python packages.
