Answer: Python Puzzler #2872

The answer is D. The program prints:

[0, 4, 8]

This answer was checked by running the program for real.

Why?

range(0, 12, 4) counts from 0 in steps of 4 and stops before 12.

The code again

print(list(range(0, 12, 4)))

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