Last thing I need to do solve is the __str__ problem. I can print the name fine, but everytime I try to put in the self.hunger and self.boredom values I get:
TypeError: Can't convert 'int' object to str implicitly http://old.nabble.com/file/p31940427/critter_caretaker3.py critter_caretaker3.py Alan Gauld wrote: > > > "Vincent Balmori" <vincentbalm...@yahoo.com> wrote > >> I'm on the Critter Caretake problem that involves handling more than >> one >> critter.
