+- 相关错误报告: http://bugs.python.org/issue10544
+- 这个bug在3.7以后的版本中不被推荐使用, 并在3.8中被修复. 因此在3.8中尝试在推导式中使用 yield, 只会得到一个 SyntaxError. 详细内容可以看[3.7更新内容](https://docs.python.org/dev/whatsnew/3.7.html#deprecated-python-behavior), [3.8更新内容](https://docs.python.org/dev/whatsnew/3.8.html#changes-in-python-behavior).
