May be you could put some parameter to your main loop:

start_point=begin
if start_point==begin: output=open('outputfile', 'w')
else                 : output=open('outputfile', 'a')

while start_point <= case <= end_point:

     try:
         do_complex_computation(case)
     except Exception:
         print case
         break

If you get an error you repair the program and set

start_point=case

and go on with the program.
