Answer: Python Puzzler #1155

The answer is A. The program prints:

[2, 6, 10]
What the program prints
Checked by running the program for real.

Why?

range(2, 14, 4) counts from 2 in steps of 4 and stops before 14.

The code again

print(list(range(2, 14, 4)))

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