Answer: Python Puzzler #933

The answer is B. The program prints:

[5, 19, 30, 46, 49]
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 = [49, 5, 46, 30, 19]
scores.sort()
print(scores)

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