我印象还停留在 2.7 和 3.6.N ……
看来 4.0 指日可待。

感觉没有很吸引人的更新，，还是继续用 Py 3.6 吧！！

@XIVN1987 PEP-567 了解一下，以前都是需要引入第三方包的。PEP-557 特定场景下少写代码，还是可以的。性能大部分情况下比 3.6 好一些，尤其是大量调用的时候，官宣 20% faster

Quoting Xiang Zhang about Chinese translations:

I have seen several groups trying to translate part of our official doc. But their efforts are disperse and quickly become lost because they are not organized to work towards a single common result and their results are hold anywhere on the Web and hard to find. An official one could help ease the pain.
