Zkus si pohrát s modulem inspect. Zaměř se na 
metody stack() a trace():

  stack( [context]) 
  
     Return a list of frame records for the caller's
     stack. The first entry in the returned list
     represents the caller; the last entry represents
     the outermost call on the stack.
  
  trace( [context]) 
  
     Return a list of frame records for the stack
     between the current frame and the frame in which
     an exception currently being handled was raised
     in. The first entry in the list represents the
     caller; the last entry represents where the
     exception was raised.

Třeba z toho to potřebné vydoluješ.
