大多数使用python的人更喜欢下划线，但即使我已经使用python 5年多了，我仍然不喜欢它们。我只是觉得它们很丑，但也许这就是我脑子里的爪哇。

I simply like CamelCase better since it fits better with the way classes are named, It feels more logical to have SomeClass.doSomething() than SomeClass.do_something(). If you look around in the global module index in python, you will find both, which is due to the fact that it's a collection of libraries from various sources that grew overtime and not something that was developed by one company like Sun with strict coding rules. I would say the bottom line is: Use whatever you like better, it's just a question of personal taste.

通常，要遵循语言标准库中使用的约定。

有一篇关于这方面的论文:http://www.cs.kent.edu/~jmaletic/papers/ICPC2010-CamelCaseUnderScoreClouds.pdf

它说snake_case比camelCase可读性更好。这就是为什么现代语言在任何可能的地方都使用(或应该使用)蛇。

就我个人而言，我尝试在类、mixedCase方法和函数中使用CamelCase。变量通常用下划线分隔(当我记得的时候)。这样我一眼就能知道我到底在调用什么，而不是所有东西看起来都一样。

列宁告诉过……我也是来自Java/ c#世界的。还有SQL。 仔细审视我自己，试图找到第一眼就能理解的复杂结构的例子，比如列表字典中的列表，其中所有东西都是对象。 对我来说，骆驼语或它们的变体应该成为任何语言的标准。在复杂句中应保留下划线。
