Confused about namespaces

[KvS]

Ok, makes sense but didn't seem "natural" to me, although it is an
obvious consequence of what you just pointed out, namely that modules
are evaluated in their own namespace, something to keep in mind... On
the other hand it does apparently work recursively "the other way
around" since I didn't explicitly import wx in main.py but only
indirect via importing GUIclasses in which wx is imported right?

Thanks. :).
