Answer: Python Puzzler #3044

The answer is B. The program prints:

[6, 8, 10, 12]

This answer was checked by running the program for real.

Why?

range(6, 14, 2) counts from 6 in steps of 2 and stops before 14.

The code again

print(list(range(6, 14, 2)))

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