I found that the workaround suggested doesn't work when you have asubclass of threading.Thread and you want to catch everything in themodule that contains the class to a common log.Say you have a module with a socket server that spawns a thread onaccept and you want to log anything that tracebacks in the module. Thisseems to work:import sysimport loggingfrom functools import wrapsdef myExceptHook(type, value, tb):    """ Redirect tracebacks to error log """    import traceback    rawreport = traceback.format_exception(type, value, tb)    report = '\n'.join(rawreport)    log.error(report)sys.excepthook = myExceptHook    def use_my_excepthook(view):    """ Redirect any unexpected tracebacks """     @wraps(view)    def run(*args, **kwargs):        try:            return view(*args, **kwargs)        except:            sys.excepthook(*sys.exc_info())    return runThen in your thread subclass:class MyThread(threading.Thread):    def __init__(self, socket_conn):        threading.Thread.__init__(self)        self.my_conn = socket_conn    @use_my_excepthook    def run(self):        """ Do stuff """
