# Practice & Exercises

> Test and reinforce your understanding of Python Functions

## Functions Practice & Exercises

To reinforce what you've learned in this section (defining functions, parameters, return values, scopes, and recursion), we have prepared two interactive Jupyter Notebooks:

<CardGroup cols={2}>
  <Card title="Follow-Along Practice" icon="laptop-code">
    Practice defining functions, default arguments, starred argument collections (`*args`/`**kwargs`), variables scopes, and recursion.

    [💻 VS Code](vscode://file/Users/sivaprasad/Downloads/python%20material/python4ai/public/notebooks/basics_exercises/Functions_Practice.ipynb) | [🚀 Colab](https://colab.research.google.com/github/prasad230776/python4ai/blob/master/public/notebooks/basics_exercises/Functions_Practice.ipynb) | <a href="/public/notebooks/basics_exercises/Functions_Practice.ipynb" download>📥 Download</a>
  </Card>

  <Card title="Practice Exercises" icon="pen-to-square">
    Test your knowledge with hands-on exercises on bill formatting, average statistics unpacking, global variables, and recursive additions.

## What's next?

Now that you know how to organize your code into files and folders, let's learn about classes - Python's way of organizing code and data together.
