Answer: Python Puzzler #2929

The answer is C. The program prints:

[2, 5, 8, 11, 14, 17]

This answer was checked by running the program for real.

Why?

range(2, 20, 3) counts from 2 in steps of 3 and stops before 20.

The code again

print(list(range(2, 20, 3)))

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