Answer: Python Puzzler #3103

The answer is B. The program prints:

[6]

This answer was checked by running the program for real.

Why?

range(6, 11, 5) counts from 6 in steps of 5 and stops before 11.

The code again

print(list(range(6, 11, 5)))

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