Main idea

Functions package reusable logic.

Tip

One function one responsibility.

Watch out

Long functions doing many jobs.

Functions is used in many real programs. Right now you are in Functional Programming.

Core idea:
Functions package reusable logic.

Read the example code on this page. Then write your own short version.

Tip:
One function one responsibility.

Watch out for:
Long functions doing many jobs.

Your challenge:
Create reusable tax calculator function.

Use the editor in the challenge lab. When your output looks correct and there is no error, press the green button to unlock the next topic.

Example code

Copy this example if it helps. Change it so it matches Functions.

# Topic: Functions
def main():
    sample = "edit me"
    # TODO: apply Functions concept here
    result = sample
    print("Result:", result)

if __name__ == "__main__":
    main()

Challenge

Create reusable tax calculator function.

Before you can finish: your output should include at least 16 characters; at least 1 non-empty line(s); no crash traceback—fix errors until the program runs cleanly.

Use Run. Read the output. Change your code until the task is done.

Starter reference

# Challenge starter for Functions
def solve():
    # Write your solution here
    pass

print("Update solve() and run")

Your code

The first Run may load Python in your browser (one-time). Later runs are faster.
