哪里在python中存储日志文件名? [英] where to store a log file name in python?

问题描述

我有一个包含几个模块的Python程序. "main"模块创建一个文件变量log_file来记录输出.其他所有模块也需要写入该文件.

I have a Python program that consists of several modules. The "main" module creates a file variable log_file for logging the output; all the other modules would need to write to that file as well.

但是，我不想将"main"模块导入其他模块，因为这将是一个非常奇怪的依赖关系(更不用说由于循环依赖关系，它甚至可能无法工作).

However, I don't want to import the "main" module into other modules, since it would be a really weird dependency (not to mention it might not even work due to circular dependency).

那么，我应该在哪里存储log_file变量?

Where, then, should I store the log_file variable?

在@pyfunc后面回答-这样可以吗:

Following @pyfunc answer - would this be ok:

--- config.py ---
# does not mention log_file
# unless it's required for syntax reasons; in which case log_file = None
# ...

--- main.py ---
from datetime import datetime
import config.py
log_filename = str(datetime.now()) + '.txt'
config.log_file = open(log_filename, 'w')
# ...

--- another_module.py ---
import config.py
# ...
config.log_file.write(some_stuff)

推荐答案

一种方法是将所有代码带入另一个模块，以便可以将其导入主文件和其他模块中.

One way is to take all that code into another module so that you could import it in main file and other modules as well.
