Answer: Python Puzzler #1241

The answer is C. The program prints:

[2, 4, 6, 8]

Checked by running the program for real.

range(2, 10, 2) counts from 2 in steps of 2 and stops before 10.

print(list(range(2, 10, 2)))

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