Answer: Python Puzzler #1246

The answer is C. The program prints:

[3, 13, 28, 31, 36]

Checked by running the program for real.

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

scores = [36, 28, 31, 13, 3]
scores.sort()
print(scores)

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