1. Packing and Unpacking

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

Packing and Unpacking Usage

Challenge: Dictionary Unpacking

Challenge: The Champions League

2. Arguments in Function

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

Arguments Overview

Challenge: Average Mark

Challenge: kwargs

3. Function as an Argument

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

High-Order Functions

Lambda Function

Built-in Functions

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.

Global Variable

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.

Introduction to Decorators

Challenge: Create Your Decorator

Decorators with Parameters

Chaining Decorators

Challenge: Basic Smores Recipe

Practical Examples of Decorator Usage

Nonlocal Variable

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:


              123456789101112
            
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:
