Answer: Python Puzzler #1271

The answer is C. The program prints:

[47, 45, 39, 27, 22, 8]

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 = [47, 39, 45, 22, 27, 8]
scores.sort(reverse=True)
print(scores)

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