CPython compiles to an intermediate form, rather than
all the way to machine code, and executes the intermediate form,
which is basically a tree, with an interpreter written in C.
ShedSkin Python compiles to C++, then all the way to machine code.
Some CPython features have to be disallowed, but there's a huge
performance gain.
Jython compiles to Java byte code, which is then compiled to
machine code by a just-in-time compiler.
Iron Python compiles to Microsoft's byte code as used by their
".NET" common language runtime. This is then compiled to machine
code by a just-in-time compiler.
