Answer: Python Puzzler #3266

The answer is C. The program prints:

[13, 23, 24, 25, 34, 38]

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 = [25, 23, 34, 24, 13, 38]
scores.sort()
print(scores)

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