Answer: Python Puzzler #3026

The answer is A. The program prints:

[1, 19, 27, 33]

This answer was checked by running the program for real.

Why?

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

The code again

scores = [19, 33, 27, 1]
scores.sort()
print(scores)

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