Answer: Python Puzzler #2982

The answer is C. The program prints:

[2, 7, 12, 17]

This answer was checked by running the program for real.

Why?

range(2, 19, 5) counts from 2 in steps of 5 and stops before 19.

The code again

print(list(range(2, 19, 5)))

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