Events are similar to a Queue that can only hold one item, but differ in two important ways: 1. calling :meth:`send` never unschedules the current greenthread 2. :meth:`send` can only be called once; create a new event to send again. They are good for communicating results between coroutines, and are the basis for how :meth:`GreenThread.wait() ` is implemented. >>> from eventlet import event >>> import eventlet >>> evt = event.Event() >>> def baz(b): ... evt.send(b + 1) ... >>> _ = eventlet.spawn_n(baz, 3) >>> evt.wait() 4 NcTt|_|dSN)set_waitersresetr s r __init__zEvent.__init__+s  rc|jjtt||j|jt |jf}d|zS)Nz)<%s at %s result=%r _exc=%r _waiters[%d]>) __class__rhexid_result_exclenr)r paramss r __str__z Event.__str__/s?.)3r$xx==, 3t}+=+=?:VCCrc\|jtus Jdt|_d|_dS)Nz#Trying to re-reset() a fresh event.rrrr s r rz Event.reset4s2|8+++-R+++  rc|jtuS)a] Return true if the :meth:`wait` call will return immediately. Used to avoid waiting for things that might take a while to time out.

The arguments to send_exception are the same as the arguments to ``raise``.
