Answer: Python Puzzler #1092

The answer is B. The program prints:

[29, 24, 22, 14, 7]
What the program prints
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 = [14, 24, 22, 7, 29]
scores.sort(reverse=True)
print(scores)

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