Nope. Python isn't a secured language in that way. I tried the same
sort of thing a while back, but found it effectively impossible. (And
this after people told me "It's not possible, don't bother trying". I
tried anyway. It wasn't possible.)

If you really want to do that, consider it equivalent to putting an
open SSH session into your debugging console. Would you give that much
power to your application's users? And if you would, is it worth
reinventing SSH?
