***1st time posting so I hope I got the rules right, but I can't for the life of me figure out why I can't see my classes displayed. Any help would be mucho appreciato, mr./mrs./ms. roboto.***
code has changed, error line number doesn't match code.
Please post code with corresponding error trace.

I apologize about the previous post, I had some comments in there that I thought weren't relevant and took them out without considering the line changes.
Thanks for the help people; Larz60+ for help posting questions properly and to buran for spotting that silly mistake.
Dunno if this might still be of actuality for you but pay attention to the way you wrote the __init__ method.
You wrote it __int__ instead of __int__ thus making your class unable to accept arguments
