Answer: Python Puzzler #3206

The answer is C. The program prints:

[0, 2, 4, 6, 8, 10]

This answer was checked by running the program for real.

Why?

range(0, 12, 2) counts from 0 in steps of 2 and stops before 12.

The code again

print(list(range(0, 12, 2)))

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