Python:更喜欢几个小模块还是一个更大的模块? [英] Python: prefer several small modules or one larger module?

问题描述

我正在开发一个Python Web应用程序，其中有一些小模块可以提供非常特定的功能:session.py，logger.py，database.py等.这些文件中的每一个目前都包含大约3-5行代码，或者最多最多10行.我可能有几个导入，每个都有一个或两个类定义.我想知道，我是否应该将这些内容合并为一个模块，例如misc.py?

I'm working on a Python web application in which I have some small modules that serve very specific functions: session.py, logger.py, database.py, etc. And by "small" I really do mean small; each of these files currently includes around 3-5 lines of code, or maybe up to 10 at most. I might have a few imports and a class definition or two in each. I'm wondering, is there any reason I should or shouldn't merge these into one module, something like misc.py?

我的想法是，使用单独的模块有助于提高代码的清晰度，以后，如果这些模块有机会增长到10行以上，那么我对分离它们不会感到很糟糕.但是，另一方面，一堆文件中只有几行似乎太浪费了！多文件方法与单文件方法之间在资源使用方面是否有显着差异? (当然，我离应该担心资源使用的地方不远，但是我忍不住要问...)

My thoughts are that having separate modules helps with code clarity, and later on, if by some chance these modules grow to more than 10 lines, I won't feel so bad about having them separated. But on the other hand, it just seems like such a waste to have a bunch of files with only a few lines in each! And is there any significant difference in resource usage between the multi-file vs. single-file approach? (Of course I'm nowhere near the point where I should be worrying about resource usage, but I couldn't resist asking...)

我四处看看是否曾经有人问过这个问题，并且没有看到Python特有的任何内容，但是如果它实际上是重复的，我将为您指出正确的方向而感激.

I checked around to see whether this had been asked before and didn't see anything specific to Python, but if it's in fact a duplicate, I'd appreciate being pointed in the right direction.

推荐答案

我的想法是分开 模块有助于代码清晰，以及 以后，如果有这些机会 模块增长到十多条线，我 拥有它们不会感到难过 分开.

这个.保持它有自己的方式.

This. Keep it the way you have it.
