I didn't say that.  I said it would work if you compiled a Python 
framework.  I said nothing of whether using the Apple-distributed 
framework would be compatible.  Applications using the stock Python 
2.3.x might (let's upgrade that to "will probably") work on both 10.3 
or 10.4, but there is no guarantee, and it's unlikely to work after

Compiling extensions on 10.3 is the only way to guarantee they will 
work on 10.3.  Testing on 10.3 is the only way to know if your app 
works on 10.3.  The degree to which you need 10.3 depends on how often 
you need to compile extensions, and how actively you're going to 
support it by testing.
