Answer: Python Puzzler #1095

The answer is C. The program prints:

[0, 5, 10, 15]

Checked by running the program for real.

range(0, 18, 5) counts from 0 in steps of 5 and stops before 18.

print(list(range(0, 18, 5)))

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