You're not moving from Python to something else; you're moving from
CPython to something else. It's like moving from Borland's C compiler
to Watcom's C compiler - all your code should still run unchanged.
There will be differences, but the bulk of your code shouldn't need
changing. With Python interpreters, the usual difference is extension
libraries - CPython can call on a bunch of things implemented in
native code, Jython can call on a bunch of things implemented in Java,
etc.
