Code Challenge
Write a calculation for five 20-minute sessions with one comment explaining the unit and no comment that merely repeats the multiplication.
Understand the idea
Write your own solution before opening the worked answer. Predict the output from the supplied values, then compare the actual result. Check both an ordinary case and the boundary described below; a passing example is more useful when you can explain why it passes.
Where to try it
Open this example with Try in playground. The code loads as editable text and does not run until you select Run. The first run downloads Python. Each run starts fresh; temporary files created by a script are not files on your PC.
Your task
Write a calculation for five 20-minute sessions with one comment explaining the unit and no comment that merely repeats the multiplication.
Show the worked solution
# Durations are stored in minutes, not seconds.
session_minutes = 20
print(5 * session_minutes)
Check the result
The total is 100 minutes.
Test one more case
Convert the total to seconds in a separate statement and keep both units clear.
