That is absolutely untrue!

Lisp and Scheme are frequently implemented in themselves -- a 
'metacircular interpreter' is a fairly typical student exercise. 

I don't know of a Python-in-Python, but I don't know of any reason
you couldn't do one. 

The only question is: how deeply do you want to emulate it? i.e.
are you allowed to use the existing parser module or do you want
to write one from scratch?
