美国时间7月12号，Python之父Guido van Rossum在Python邮件组里发邮称要退出Python核心决策层，而转居幕后。
I would like to remove myself entirely from the decision process. I'll
still be there for a while as an ordinary core dev, and I'll still be
available to mentor people -- possibly more available. But I'm basically
giving myself a permanent vacation from being BDFL, and you all will be on
your own.

此消息在Twitter的Python圈里引起了轩然大波。
过去一段时间，莽爹一直在为PEP572的通过而努力，https://mail.python.org/pipermail/python-dev/2018-July/154557.html 然而此过程并不顺利，出现了大量的反对声音，莽爹也是精疲力竭了估计。
不管咋样，还是感谢莽爹，感谢莽爹创造了Python和为此付出半生的努力。
