You can also use this technique to overload .__init__(), which will allow you to provide multiple implementations for this method, and therefore, your class will have multiple constructors. Remove ads A Real-World Example of a Single-Dispatch Method As a more realistic example of using @...

这在由Tim Peters写的Python格言(称为The Zen of Python)里面表述为:There should be one-- and preferably only one --obvious way to do it. 这正好和Perl语言(另一种功能类似的高级动态语言)的中心思想TMTOWTDI(There's More Than One Way To Do It)完全相反。

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...
