Is Python unsuitable? No, it can probably be made to work. It is just a question of performance, and effort needed to integrate it.
Will a Python implementation run slower and use more memory than a Lua one? Probably.
what other requirements were you thinking of that would be helped with a Python implementation?
You don't need to be afraid of Lua. It is a nice little language, kind of like a Scheme wrapped in a Python syntax.
