Sorry for the confusion; fooz(), track() and barz() are all members of their
respective classes. I must have missed the self argument while creating the
synthetic example.
Yeah, I realize the mutual import is a bad idea. So, if I merge them into a
single module (but still retaining the two classes) will work right?
Yes, if you define them both in the same module, they can reference each
other arbitrarily. But you still have plenty of errors, some of which
Chris has pointed out. I can ignore most, but his point about calling a
function without an instance is important, so I'll comment some more at end.
I
guess, it will look like this after merging.
Thanks again

You can't call an instance method on a class.
If you really need to call this on the class (because its data spans
multiple instances, for example), then you should make it a
classmethod. Easiest way is as follows:
class Foo:
def fooz(self):
print "Hello World"
b = Bar()
c = b.barz()
...
@classmethod
def track(cls, track_var):
count += 1
Note that the first argument is now the class, so by convention we call
it cls, rather than self. And that within a class method, you typically
reference class attributes. So you might want to use something like:
class Foo:
count = 0 #I'm a class attribute
def fooz(self):
print "Hello World"
b = Bar()
c = b.barz()
...
@classmethod
def track(cls, track_var):
cls.count += 1
