Is there any Python equivalent to partial classes?

Question

Using \"new\" style classes (I\'m in python 3.2) is there a way to split a class over multiple files? I\'ve got a large class (which really should be a single class from an

I've not used it, but this package called partial claims to add support for partial classes.

It seems like there's a few other ways you could implement this yourself as well.

You could implement separate parts of the class as mixins in seperate files, then import them all somewhere and subclass them.

Alternatively, you could implement each of the methods of your class somewhere then in a central file import them and assign them as attributes on a class, to create the whole object. Like so:

a.py:

def AFunc( self, something ):
    # Do something
    pass

b.py:

def BFunc( self, something ):
    # Do something else
    pass

c.py:

import a, b

class C:
    AFunc = a.AFunc
    BFunc = b.BFunc

You could even go so far as to automate this process if you really wanted - loop through all the functions provided by modules a and b and then add them as attributes on C. Though that might be total overkill.

There might be other (possibly better) ways to go about it, but those are the 2 that popped into mind.
