Answer: Python Puzzler #3075

The answer is A. The program prints:

[2, 6, 10, 14]

This answer was checked by running the program for real.

Why?

range(2, 18, 4) counts from 2 in steps of 4 and stops before 18.

The code again

print(list(range(2, 18, 4)))

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