Answer: Python Puzzler #842

The answer is D. The program prints:

[3, 7, 11]
What the program prints
Checked by running the program for real.

Why?

range(3, 15, 4) counts from 3 in steps of 4 and stops before 15.

The code again

print(list(range(3, 15, 4)))

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