Mainly that it helps to actually show your code, or at least as much of
it as you think we might be interested in.
Good job showing us the versions & os, and the full traceback.
No idea why it works in pycrust; I've never used it, or pyshell. It's
not clear what you mean by "typing in the shell". if you mean you're
entering it in the interpreter, then I'd guess you didn't indent it the
same way as in the file.
But if it doesn't work at the command line, it's broken. And my guess
is that you're trying to use the class inside its own definition.
That's okay inside a method, but not inside the class initialization.
For example, if you have
app = myapp_tk(None)
it's not valid. Instead, do the following after the class definition is
myapp.app = myapp_tk(None)
BTW, it's customary to capitalize the first letter of a class name.
