PYTHON LESSON
match/case
match routes execution by exact pattern/value.
Use for menu-style choices.
Using match where simple if is clearer.

This lesson is about match/case. You are in the Logic part of the course.
Main idea:
match routes execution by exact pattern/value.
How to learn it: type a very small program first. Run it. Change one line and run again.
Tip:
Use for menu-style choices.
Common mistake:
Using match where simple if is clearer.
Your challenge:
Menu program with options 1 to 4.
Scroll down to the challenge lab. Run your code there. When the output meets the task and the checks pass, press the green button to finish this topic.
Example code
Copy this example if it helps. Change it so it matches match/case.
# Topic: match/case
def main():
sample = "edit me"
# TODO: apply match/case concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Menu program with options 1 to 4.
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.
