Komodo has a Python built-in. It isn't meant to be directly used. It is
just necessary to get Komodo to run because Komodo has a lot of Python
code in it.

Internally, Komodo uses its own Python. When you run your script, Komodo
uses your "system Python". So you could install a Python 1.5 or 2.1 and
Komodo would work with it even though Komodo itself uses Python 2.0
internally. Komodo's Python is just a component it uses -- it isn't
exposed to end users. Pretend it isn't there.

Many large applications will ship their own Pythons to avoid
accidentally picking up a wrong-versioned Python, or a Python with a
weird extension etc. Komodo and Zope are two examples.

BeOpen Python is a standalone Python distribution so you could install
ActivePython over it without losing anything. Zope and Komodo ship
internal Pythons for a reason and you should not replace them. As I
said, the bundled Python in Komodo is just a component that should be
invisible to end-users. Maybe next time we'll call it nohtyP.exe .
