how to use "exec" stmt to get input from user

What you're trying to do and what's not working isn't 
entirely clear to me.

But if I had a wxPython application and I wanted to
execute user input (note the _if_) I'd just pop up a window
(I forget how "ShowModal" is spelled in wx right now)
with a text box and an Execute button and a Cancel
button - if the user hits the Execute button I'd
attempt to execute what he'd typed in the box.

There are reasons you want to be very careful about
