I don't think it exists.
I think that would be a difficult thing to do in a generic way.
The potential for inadvertant data loss is very high.

I assume you mean something like:

def forceInt(v, default=42):
   try: result = int(v)
   except: result = default
   return result

but if you do 

class C: # lots of stuff in here
    pass
c = C()

v=forceInt(c)

You could lose all the data in C.    
I suppose that if you make the default non defaulted - so you have 
to provide a default - that would be better, the default could then 
be the object itself

v = forceInt(c,c)

Is that what you mean?
