Answer: Python Puzzler #2992

The answer is D. The program prints:

[1, 5, 12, 37]

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 = [37, 1, 5, 12]
scores.sort()
print(scores)

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