如何正确创建实用程序类 [英] How to create an utility class correctly

问题描述

我有一个文件，意思是一个实用程序文件。
该文件应该包含许多静态方法。

I have a file that meant to be an utility file. The file should contain alot of static methods.

我应该通过这种方式定义类中的方法：

Should i define the methods inside a class this way:

#utility.py
class utility(object):
    @staticmethods
    def method1(a,b,c):
        pass

    @staticmethods
    def method2(a,b,c):
        pass

或者像这样使用它（没有类）：

or use it like this (without a class):

#utility.py
def method1(a,b,c):
    pass

def method2(a,b,c):
    pass

推荐答案

第二个选项是python中的操作方式。我的意思是，如果你所做的是导入函数，那么你可以这样做：

The second option is the modus operandi in python. I mean, if all you're doing is importing functions, then you can do something like this:

from utility import some_func

这将导入您的函数。

最佳实践是，如果你只使用静态函数，那么只需将它们放在一个单独的模块的全局命名空间中，它将使你的生活更容易。你想做的是制作对象，并用静态方法填充它们。为什么要这样做，当你可以在 .py 文件中定义函数？

Best practice is, if you're using only static functions, then just put them in the global namespace of a separate module, it will make your life a lot easier. What you're trying to do is make objects and just fill them in with static methods. Why do this, when you can just define the functions in a .py file?

尝试已完成。你试图存储一些好的效用函数。好了， python-requests 是一个第三方库，只是被大多数pythonistas所喜欢。它将其良好的效用函数存储在单独的模块中。 以下是示例

In fact, what you're trying to do has been done. You're trying to store away some good utility functions. Well, python-requests, is a third party library that is just adored by the majority of pythonistas just does this. It stores away its good utility functions in a separate module. Here is the example.
