you can dissect traceback, frame, and
code objects to get the required info.
here's an example:
"""
import sys, traceback
try:
    execfile("script.py")
except Exception, argument:
    et, ev, tb = sys.exc_info()
    while tb:
        co = tb.tb_frame.f_code
        print co.co_filename,
        print traceback.tb_lineno(tb)
        tb = tb.tb_next
    print et, ev
