Are you using 2.8? if so then there is a CurrentSelection Property -- I 
don't know if it can take a string, or just an index. Otherwise,

wx.Choice.SetSelection and wx.Choice.SetStringSelection

are derived from ItemContainer -- all these nested classes so make it 
hard to find things!

I'm not sure I follow, but:

A) you can either get and set selections by index number or string -- I 
like to use strings, otherwise I need to keep a separate list or dict to 
map strings to indices.

B) This is what I do when using a wx.Choice:

1- populate the Choice on construction:
2- Set a default Choice on construction -- this may well be just index0, 
but sometimes there is a reason to have a particular default.
3- bind  EVT_CHOICE to a method that does somethign with the choice
4- Usually have a method to set the choice, if it is set somewhere else 
in the program.

2 and 4 require SetStringSelection.
