4. Variable Scope

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.

Challenge: Modifying a Global Variable

Nested Functions

Nonlocal Variable

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.

Local Variable

A local variable is defined inside a function. You cannot access this variable outside the function's definition.


              123456
            
def greet():
    message = "Aloha"
    print(message, "# local message")

greet()
print(message)  # This line will result in an error

The output is:

The message variable is not accessible in the global scope; it exists only inside the function. When the function exits, this variable ceases to exist.
