Use the builtin function `getattr` on the module that contains
the class named "Foo".
For example:
module.Foo
is equivelant to:
getattr(module, "Foo")
Here is an interactive session:
py> import Tkinter
py> Tkinter.Label
<class Tkinter.Label at 0x023BE5A8>
py> getattr(Tkinter, "Label")
<class Tkinter.Label at 0x023BE5A8>
