@ClericPy 3.8 等待中...
pyenv 现在只有 rc4. 等出了 3.8, docker 也出了以后, 部分项目就可以先上了.

回复了 ClericPy 创建的主题 › Python › Python 3.7+ 想验证一个对象是否符合 typing.Dict[str, int] 应该怎么做?

@ClericPy 改用 pydantic 搞定很多类型严重和转换问题.

官方提供了 speed 对比. 采用 3.6 位基准, 3.7 和 3.8 有明显的提升.
采用 3.7, 看 3.8, 部分测试各有优劣.

@wuwukai007 https://docs.python.org/3.8/whatsnew/3.8.html#optimizations 看了下优化部分, 还是挺明显的.

Improved performance of operator.itemgetter() by *33%*. Optimized argument handling and added a fast path for the common case of a single non-negative integer index into a tuple (which is the typical use case in the standard library).

Sped-up field lookups in `collections.namedtuple()`. They are now more than two times faster, making them the fastest form of instance variable lookup in Python.

The list constructor does not overallocate the internal item buffer if the input iterable has a known length (the input implements __len__). This makes the created list *12%* smaller on average.

Reduced an overhead of converting arguments passed to many builtin functions and methods. This sped up calling some simple builtin functions and methods up to *20–50%*.

LOAD_GLOBAL instruction now uses new “per opcode cache” mechanism. It is about *40%* faster now.

回复了 szzhiyang 创建的主题 › 程序员 › 同是静态类型检查，为什么 Python 圈对 Type Hints 的重视程度明显不及前端圈对 TypeScript 的重视程度？

ts 的重视因为是一门新语言, 然后翻译成 js 执行.

python 自带 typing, 但是并不是强制的.
