print()函数不支持老print语句的“软空格”特性,例如,在python2.x中,print "A\n", "B"会输出"A\nB\n",而python3.0中,print("A\n", "B")会输出"A\n B\n" 学会渐渐习惯print()吧! 使用2to3源码转换工具时,所有的print语句被自动转换成print()函数调用,对大项目,这是无需争论的。 py
A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to define asynchronous generators: async def ticker(delay, to): """Yield numbers from 0 to...

This is the error I would expect if you didn't have quotes around the numbers. I'm not sure why it's happening, because I copied your YAML exactly and it seemed to work. Maybe it would help to put a print command in alerts.py right before the subprocess.Popen command to see what ...
