Answer: Python Puzzler #3220

The answer is B. The program prints:

[0, 3, 6, 9]

This answer was checked by running the program for real.

Why?

range(0, 11, 3) counts from 0 in steps of 3 and stops before 11.

The code again

print(list(range(0, 11, 3)))

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