I wrote the below code

    class _Timelimited(Process, ):
        _error_ = TimeLimitExpired
        _result_ = None
        def run(self):
            try:
                self._result_ = function(*args, **kwds)
            except Exception as e:
                e.orig_traceback_str = traceback.format_exc()
                self._error_ = e
            else:
                self._error_ = None
        def _stop(self):
            if self.isAlive():
                _Thread_stop(self)
    if (not hasattr(function, '__call__')):
        raise TypeError(('function    not    callable:    %s' % repr(function)))
    if (timeout is None):
        return function(*args, **kwds)
    if (timeout < 0):
        raise ValueError(('timeout    invalid:    %s' % repr(timeout)))
    t = _Timelimited()
    t.start()
    t.join(timeout)
    if (t._error_ is None):
        return t._result_
    if (t._error_ is TimeLimitExpired):
        t._stop()
        raise TimeLimitExpired(('timeout    %r    for    %s' % (timeout, repr(function))))
    else:
        raise t._error_

What's a good function header?

Here's a good function header?
