well the __init__() funciton is not my code, it is in:
as I mentioned I upgraded wxpython... maybe I should email there... anyhow I just want to use my dictionary in the shell, but I'm not sure what the attribute 'this' is... it seems to be something different from my previous version of wxpython.

other is whatever you pass in.
The code expects it to be dictionary like and to 
have a this attribute

So why is your code trying to access one if you know 
it doesn't exist? And why are you surprised at the 
error message? (Or is the init() not your code?)

Youu seem to have answered your own question.
You are passing a dictionary into init() that does not 
have a this attribute but the code inside the init() is 
trying to access a this attribute. It can't find one so 
it raises an error.

Either remove the this access in init or add a thus 
attribute to your dictionary argument. Or pass an 
argument that does have a this attribute.

I'm slightly confused about what you are asking us to tell you?
