Addind imports to a class namespace

[Ryan K]

Thanks for your help Peter.

I'm thinking that perhaps this isn't a circular import and that I
don't understand importing. Here is a better explanation of my case (I
am using Django):

I have file x.py that declares classes A, B, C.

There is also a file y.py that contains two methods T, U and the class
that we are talking about above.

x.py uses a dispatcher system to connect a signal to methods T and U
in y.py so it does: from y import T, U.

y.py needs to use classes A, B, C which is basically Menu and Link
(and some other class) above so I am thinking that if in y.py I have
from x import A, B, C that will cause a circular import?

Is this not correct and if it isn't can you explain why? Does using
from ... import X, Y, Z, i.e. explicit imports avoid this problem or
does it exacerbate it?

Thanks,
Ryan
