This is definitely true, no matter the language you use.

If you're really interested in interfaces you might want to check out 
Zope3.  Even if you don't want to use the "web" parts, the component 
architecture parts (interfaces, adapters, etc.) might be interesting to you.

In a related vein is PEAK (http://peak.telecommunity.com/).  It also has 
some related ideas about interfaces, components, adapters, etc.

I don't quite follow here.  Are you talking about using a method like 
"thing.getX" instead of just accessing the attribute directly like 
"thing.x"?  If so, that kind of up-front design isn't necessary in Python.

Refactoring *is* the way you handle not being able to "[design] the 
software interactions completely bevorehand".
