Answer: Python Puzzler #1038

The answer is D. The program prints:

[28, 27, 25, 8, 5, 1]

Checked by running the program for real.

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

scores = [5, 28, 1, 8, 25, 27]
scores.sort(reverse=True)
print(scores)

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