Python：从包含当前文件的文件中调用函数 [英] Python: Calling a function from a file that has current file imported

问题描述

我试着四处搜寻，但似乎没有找到我的问题的答案，所以我很抱歉，如果我错过了一些东西，它实际上已经回答过。

<所以基本上我有main.py和另一个名为check.py的文件（两者都在同一个目录中）

在我的main.py中我有：

  from check import checkfunction 
  

我在main.py中有一个小函数，我必须在check.py中调用，但我似乎无法得到这个导入在我的check.py上工作：

  from main import main函数
  

如何获取主函数在check.py中工作？

谢谢！

解决方案

选项：
$ b

• 将公共函数移动到由其他模块导入的模块中。 合并两个模块合并为一个。


• 将函数从main传递给需要调用它的代码。



• 重新整理所有东西，使得你没有循环依赖。

如果你真的解释了为什么你有这个设计，有人可能会提出一个更好的方法。




I tried searching around but didn't seem to find an answer to my problem, so I'm sorry if I missed something and it actually has been answered before.

So basically I have main.py and another file called check.py (both in same directory)

In my main.py I have:

from check import checkfunction

I have a small function inside main.py that I MUST call inside check.py, but I can't seem to get this import working on my check.py:

from main import mainfunction

How can I get the mainfunction to work inside check.py?

Thanks!

解决方案

Several options:

• Move the common function to a module imported by both other modules.
• Merge both modules into one.
• Pass the function from main to the code that needs to call it.
• Monkey patch the function into the check module after importing it.
• Refactor the whole thing so that you don't have circular dependencies.

If you actually explained why you have this design, someone could possibly propose a better way.
