Answer: Python Puzzler #1057

The answer is A. The program prints:

[7, 38, 39, 40, 45, 46]
What the program prints
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 = [40, 7, 46, 38, 45, 39]
scores.sort()
print(scores)

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