This could be coded more succinctly as

import sys, traceback

def get_traceback(): # obtain and return the traceback
    return ''.join(traceback.format_exception(*sys.exc_info()))

Errhm, '%s' % get_traceback() is equiavalent to get_traceback()
How about:

if __name__ == '__main__':
    try:
        Runs_unattended()
    except:
        send_mail(send_from = yourEmailAddress,
              send_to = [ yourEmailAddress ],
              subject = 'Runs_unattended',
              text = get_traceback(),
              files = [],
              server=yourLocalSMTP)



Hope this helps,
