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().

答

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
