1. What is a Function?

Functions are one of the most important components of any programming language. Here we will learn how to create simple functions and see how use them to simplify the code

What is a Function?

Challenge: Create a More Complex Function

Challenge: Create a Function 'exam_scores' with if-else Statement

Challenge: Calculate the Ellipse Area

Print vs Return

2. Arguments or Parameters

Parameters and arguments are a piece of information that is passed to a function. Here we will learn how to work with them.

Arguments or Parameters

3. Assigning a Default Value to a Parameter

In this section, we will learn what default parameters are and what they are used for. We will also learn how to create functions with them.

Default Parameters

4. An Unknown Number of Arguments

What if we don't know exactly how many arguments we will send? Here we will learn how to fix this problem.

Unknown Number of Arguments

5. Functions within Functions

Here we will learn how to create functions that are defined inside another function, and they are called inner or nested functions.

Functions within Functions

6. Recursion

Recursion is a general mathematical and programming concept. Here we will learn how to implement recursive functions.

Task

You have to implement a function called numbers(), which has three parameters: x, y, z with a default value of x = 10. This function should display the sum of these three numbers if y is greater than 33; if y is less than 33, then the function should display the product of these three values. The input for this function will be 34, 6274.
