So, now we understand the difference between **global** and **local variables** and have learned about **nested functions**.
The ***nonlocal*** variable is used in nested functions.
Let's look at an example:

def outer_function():
    outer_var = 10 

    def inner_function():
        nonlocal outer_var
        outer_var += 5
        print("Nonlocal variable in inner function:", outer_var)

    inner_function()
    print("Nonlocal variable in outer function:", outer_var)

outer_function()

Just as with global variables, we cannot change the variable created in `outer_function` inside `inner_function` without using the special keyword ***nonlocal***.

The output is:
``` python
Nonlocal variable in inner function: 15
Nonlocal variable in outer function: 15
```

In this course, you will learn advanced topics such as function arguments, iterators, generators, closures, and decorators. Dozens of practice exercises will help you grasp these topics.

You'll find this topic enjoyable, and you'll learn how to pack and unpack values in a single assignment.

Explore the power of Python's function arguments, *args, **kwargs, and learn how to effectively use functions as arguments.

Discover the higher-order functions and how functions can be passed as arguments to other functions in programming.

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.

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.
