Answer: Python Puzzler #1179

The answer is D. The program prints:

[11, 13, 21, 23, 40, 44]

Checked by running the program for real.

sort() puts the list in order, smallest first. It changes the list itself.

scores = [13, 44, 21, 23, 40, 11]
scores.sort()
print(scores)

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