It's a little difficult to visualise what you're describing, but IIUC
your problem is of this form:
===== foo.py =====
import bar
class Foo(bar.Bar):
pass
=====
===== bar.py =====
import baz
class Bar(baz.Baz):
pass
=====
===== baz.py =====
import foo
class Baz(foo.Foo):
pass
=====
That is, each of the classes want to inherit from the others.
The usual solution in these cases is to find the common required
functionality and factor that out to a separate class that is then the
superclass of two of the existing classes, breaking the circle.
===== wibble.py =====
# no dependencies
class Wibble(object):
pass
=====
===== foo.py =====
import wibble
import bar
class Foo(wibble.Wibble, bar.Bar):
pass
=====
===== baz.py =====
import wibble
class Baz(wibble.Wibble):
pass
=====
Note that Baz no longer subclasses foo.Foo, and both Foo and Baz get
the common functionality they share from wibble.Wibble.
