Answer: Python Puzzler #1016

The answer is A. The program prints:

[4, 6, 8]

Checked by running the program for real.

range(4, 9, 2) counts from 4 in steps of 2 and stops before 9.

print(list(range(4, 9, 2)))

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