I figured out why it was asking for the radius of a square. It was because I
had the if shape==1: thing on there. I was typing in rectangle and that was an
else: function. How do i get it to accept both 1 and circle? I learned not to
use else: unless I was completely sure that I could use it, to avoid problems
like this.I put both the .py and .txt files on there, so which ever you
prefer.Thanks,Adam> To: tutor@python.org> From: [EMAIL PROTECTED]> Date: Sat,
