Answer: Python Puzzler #1214

The answer is B. The program prints:

[0, 2, 4, 6, 8, 10, 12, 14, 16]

Checked by running the program for real.

range(0, 18, 2) counts from 0 in steps of 2 and stops before 18.

print(list(range(0, 18, 2)))

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