Answer: Python Puzzler #2927

The answer is D. The program prints:

[44, 36, 24, 13, 9]

This answer was checked by running the program for real.

Why?

sort() puts the list in order, smallest first. reverse=True flips it, so the biggest comes first. It changes the list itself.

The code again

scores = [44, 13, 36, 9, 24]
scores.sort(reverse=True)
print(scores)

Try it: change one number in the program and predict the new output before you run it.
