Answer: Python Puzzler #978

The answer is C. The program prints:

[46, 40, 12, 11, 8, 7]

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 = [11, 8, 7, 46, 12, 40]
scores.sort(reverse=True)
print(scores)

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