Module 17: Function Parameters Practice

Anatomy of a Function Definition Abstraction

Functions bundle code. Let's dissect how we define one. Click each highlighted part of the function definition below.

                         def greet(name):
                         
    # Code block goes here (indented)

Identify all 6 parts!

Parameter & Argument Matching

When you *call* a function, you pass *arguments* that fill the *parameters*. Click a parameter in the definition, then click the corresponding argument in the call.

Function Definition
                                 def calculate(a, b):
                                 
    # Does something
                             

Function Call
                                 calculate(10, 5)
                             

Click a parameter (like 'a')...

Practice Calling a Function

We've defined a function `say_hello` for you below. In the editor, write the Python code to *call* this function, passing the string "AI" as the argument.

Defined Function:

                         def say_hello(person_name):
                         
    print("Hello, " + person_name + "!")

Your Code (Function Call):

Simulated Output:

Output will appear here...

Spot Parameter vs. Argument

Parameters are in the definition, arguments are in the call. Click the parameter in the first line and the argument in the second line. Then check!

def set_power(level): # Definition

set_power(9000) # Call

Mini Missions: Functions!

Time to build and use your own functions! Complete these tasks. Decomposition helps break tasks into functions.

Mission 1: Announce Topic

Define a function named `announce` that takes one parameter called `topic`. Inside the function, print the phrase "Let's discuss " followed by the value of the `topic` parameter.

Define the function... (no output expected yet)

Mission 2: Add Two Numbers Decomposition

Define a function `add_numbers` that takes two parameters, `x` and `y`. Inside, it should print the *sum* of `x` and `y`. Then, on a new line *after* the definition, *call* the function with the arguments `5` and `3`.

Mission 3: Repeat Message

A function `repeat_message(msg, times)` is pre-defined (you don't need to write it). Write the code to *call* this function to print the message `"Go! "` (note the space) exactly `3` times.

Module 17 Practice Complete!

Excellent! You've practiced defining functions, using parameters, and passing arguments. This is key for reusable code! Abstraction
