Answer: Python Puzzler #1243

The answer is B. The program prints:

[6, 15, 17, 44, 45]

Checked by running the program for real.

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

scores = [44, 15, 17, 45, 6]
scores.sort()
print(scores)

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