Module 18: Function Returns Practice

Spotlight on `return`

Functions can send back results using `return`. Click the highlighted parts of this simple function to see what they do. Notice how this supports Abstraction.

                         def add_numbers(num1, num2):
    return num1 + num2
                     

Identify all parts!

Predict the Returned Value

When the code below runs, what value will the function calculate_area *return*? Type your answer in the box.

                         def calculate_area(length, width):

                             area = length * width

                             return area

                         result = calculate_area(5, 4)

                         print(result) # This will print the returned value

The function returns:

Build-a-Function

Drag the pieces below to create a function named greet that takes one parameter name and *returns* the string "Hello, [name]!". This task involves Decomposition.

Code & Use Return

Write a function called get_initial that takes a name (string) as input and *returns* only the first letter (initial) of the name. Then, call this function with a name (e.g., "Alice") and print the returned initial.
