如果你需要某个Python函数或语句的快速信息帮助,那么你可以使用内建的help功能。尤其在 你使用带提示符的命令行的时候,它十分有用。比如,运行help(str)——这会显示str类的帮 助。str类用于保存你的程序使用的各种文本(字符串)。按q退出帮助。 Python2和python3 版本不

So far, we’ve only been working with supplying mocks for functions, but not for methods on objects or cases where mocking is necessary for sending parameters. Let’s cover object methods first. We’ll begin with a refactor of thermmethod into a service class. There really isn’t a justif...
