Python suitable for a game engine?

Don't want to put the cat amongst the pigeons but Lua
(http://www.tecgraf.puc-rio.br/lua/), is a language specifically designed to
be embedded and it runs about 50-100% faster than Python and is a lot more
compact (30k or something). It has a lot of similarities syntactically as
far as I can see.

 If I was to use an embedded scripting language in a game I would use Lua
not Python. If I was to write tools for the game I would use Python.

Cheers,
Nick.
