Answer: Python Puzzler #2983

The answer is A. The program prints:

[46, 44, 28, 8]

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 = [8, 28, 46, 44]
scores.sort(reverse=True)
print(scores)

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