如何导入datetime.now，以便我可以使用now()进行调用?

问题描述

我希望能够在程序中调用datetime.now().

I want to be able to call datetime.now() in my program.

• import datetime要求我做datetime.datetime.now()
• from datetime import datetime仍然需要我做datetime.now()
• from datetime.datetime import now无法编译

• import datetime requires me to do datetime.datetime.now()
• from datetime import datetime still requires me to do datetime.now()
• from datetime.datetime import now doesn't compile

有没有一种方法可以导入它，而不必指定父类? IE.我希望能够执行t = now()而不是t = datetime.now().

Is there a way to import it so that I don't have to specify the parent classes? Ie. I want to be able to do t = now() as opposed to t = datetime.now().

推荐答案

您不能直接导入datetime.datetime.now，因为datetime不是不是模块，它实际上是一个类，并且now是一种分类方法. 这里是有关导入静态方法的类似问题.

You can't import datetime.datetime.now directly because datetime is not a module, it is actually a class, and now is a classmethod. Here is a similar question regarding import static methods.

这是一个最小的工作代码，可以执行您需要的操作.

Here is a minimal working code to be able to do what you need.

import datetime
now = datetime.datetime.now
