Answer: Python Puzzler #971

The answer is C. The program prints:

[3, 8, 13]

Checked by running the program for real.

range(3, 16, 5) counts from 3 in steps of 5 and stops before 16.

print(list(range(3, 16, 5)))

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