Answer: Python Puzzler #1042

The answer is C. The program prints:

[5, 8, 11]
What the program prints
Checked by running the program for real.

Why?

range(5, 13, 3) counts from 5 in steps of 3 and stops before 13.

The code again

print(list(range(5, 13, 3)))

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