Answer: Python Puzzler #1252

The answer is A. The program prints:

[0, 4, 8, 12]
What the program prints
Checked by running the program for real.

Why?

range(0, 13, 4) counts from 0 in steps of 4 and stops before 13.

The code again

print(list(range(0, 13, 4)))

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