You could wrap the Python code you call in a try/except, then catch and save
the exception:

    import traceback, sys
    try:
        ... original code ...
    except:
        traceback.print_tb(sys.exc_info()[2], 0, open("/tmp/traceback", "w"))
	raise

The raise call is there so the return value of PyRun_SimpleFileExFlags is
the same.  It's not strictly necessary.
