Answer: Python Puzzler #3095

The answer is C. The program prints:

[4, 6, 8, 10, 12, 14, 16, 18]

This answer was checked by running the program for real.

Why?

range(4, 19, 2) counts from 4 in steps of 2 and stops before 19.

The code again

print(list(range(4, 19, 2)))

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