note you're just defining some local variables here, should be self.b = B()
and self.c = C().

You could do it manually:
c = getattr(getattr(a, 'b'), 'c')
or make it automatic:
def get_dotted_attr (obj, dotted_attr) :
for attr in dotted_attr.split('.') :
obj = getattr(obj, attr)
return obj
a = A()
print 'a.b.c = %s' % get_dotted_attr(a, 'b.c')
