What is variable scope, and how did we manage without it before? This topic is essential for understanding the following subjects: Closures and Decorators. I assure you that this topic will be both enjoyable and practical. You will gain knowledge about local, nonlocal, and global variables.

Global Variable

Challenge: Modifying a Global Variable

Nested Functions

Nonlocal Variable

Closures

Challenge: Threshold Checker

5. Decorators

This section provides an in-depth exploration of Python decorators, a powerful feature that allows for the modification and enhancement of function behavior. Participants will learn how to write their own decorators, understand built-in decorators, and apply decorators in practical scenarios.

Challenge: Average Mark

Tarea

Let's calculate the average mark for the student. Each student has a different number of marks, so we don't know how many arguments will be passed to the function.

Set the first positional argument as name in the average_mark function;
For other arguments use *args;
In the equation that counts the mark variable use args without *;
In the print statement use name and mark variables.
