Being 'compiled' or 'interpreted' is not a feature of a language, but of 
a given implementation of a language (and even then, some 
implementations of some languages supports both).

wrt/ CPython (the reference implementation), it is actually compiled to 
byte-code - just like Java. The main difference being that the VM is 
smart enough to automagically (re)compile what's needed.
