Post some sample code, and show what doesn't work;  maybe you'll get some help that way.

I'll point out just one thing:  you cannot add new local variables at runtime.  locals() should be used to inspect, not to modify.

See the help text:
  "The contents of this dictionary should not be modified; changes may not affect 
the values of local variables used by the interpreter"

I have no idea if exec() can be safely called recursively.  Most people successfully avoid calling it at all.
