Answer: Python Puzzler #3057

The answer is A. The program prints:

[18, 27, 30, 34]

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 = [18, 30, 34, 27]
scores.sort()
print(scores)

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