Re: [Tutor] Local Unbound Mystery

[Wayne Watson]

Yes, I read it and tried the global statement with the same results, and tried it without the keyop set. It gave a prompt, and died as before.   Now I've inserted the global statement in the function and it  works by print out the value of updown inside the function.  Beats me. (read below) I do not think I've made an inaccurate observation. Is it possible the IDLE shell is leaving something behind that I can't see? Maybe I had two shell window up at the same time between the real and debug program. I just started from scratch with the debug program minus the keyop set, and Python discovered it wasn't set. Oh, well. Gads. I just changed the def function name, and it ran! I now changed the def function name again, and it ran. Oh, boy. I now have closed all IDLE windows, and tried the debug again. It catches the misnamed function. Yikes! I just inserted the global statement in the full program, and it's working. This was not the case yesterday. I give up trying to explain this. It works as it should, so I'm going to continue making the mods before all this happened.

Not really the code has an error so it could not have worked. updown = +1 while keyop <> 0: You forgot to create keyop in this example.
