Answer: Python Puzzler #843

The answer is D. The program prints:

[4, 9, 14]

Checked by running the program for real.

range(4, 17, 5) counts from 4 in steps of 5 and stops before 17.

print(list(range(4, 17, 5)))

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