python yield 关键字：
yield是用于生成器。什么是生成器，你可以通俗的认为，在一个函数中，使用了yield来代替return的位置的函数，就是生成器。它不同于函数的使用方法是：函数使用return来进行返回值，每调用一次，返回一个新加工好的数据返回给你；yield不同，它会在调用生成器的时候，把数据生成object，然后当你需要用的时候，要用next()方法来取，同时不可逆。你可以通俗的叫它"轮转容器"，可用现实的一种实物来理解：水车，先yield来装入数据、产出generator object、使用next()来释放；好比水车转动后，车轮上的水槽装入水，随着轮子转动，被转到下面的水槽就能将水送入水道中流入田里

python 的打包 发布

Python 打包：

Python 库打包的格式包括 Wheel 和 Egg。Egg 和 Wheel 本质上都是一个 zip 格式包，Egg 文件使用 .egg 扩展名，Wheel 使用 .whl 扩展名。Wheel 的出现是为了替代 Egg，其现在被认为是 Python 的二进制包的标准格式。两者区别：https://packaging.python.org/discussions/wheel-vs-egg/
