Hi, Sorry to say but these don't satisfy my issues. 1 the next code SHOULD produce an error message. Think that it's followed by a few dozens of code lines: from turtle import * fd; rt(90) 2 Old Logo had a useful function of creating a circle AROUND THE TURTLE. It would be very nice it such a function was built-in in Python's turtle module. Giving this to student as a problem is not a good answer, it's more like a sort of "pass the baby" solution. Thank you for the fast reply.
