Answer: Python Puzzler #3107

The answer is C. The program prints:

[5, 10, 15]

This answer was checked by running the program for real.

Why?

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

The code again

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

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