working with multiple frame instances

[fchef]

I am looking for some advice on working with Multiple frame instances.
Essentially I need to be able to refer to specific control values in a
frame and be able to hide/show a specific frame. In VB you can
reference a particular frame with something like Controls.Form("My
form").DoSomething. Is there something analogous to this in Python? Or
is there a better approach all together?
