Answer: Python Puzzler #1134

The answer is D. The program prints:

[7, 16, 29, 40, 42, 45]
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 = [7, 40, 42, 29, 16, 45]
scores.sort()
print(scores)

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