Re: Binary tree problem (searching)

This took a moment
I spent a lot of time stupidly thinking about right/left sorting, is it
looping?  no that's not it...doh Then the light

then realized this

         if self.key == key:
            return 1
        elif key < self.key:
            if self.left:
                self.left.find(key)
            else:
                return -1


you need to  RETURN on the child call -

            if self.left:
                self.left.find(key)

becomes
            if self.left:
                return self.left.find(key)
