David Goodger(在这里的“像Pythonista一样编码”中)描述了PEP 8的建议如下:

Joined_lower函数，方法， 属性、变量 joined_lower或ALL_CAPS for 常量 课程用的studlycap 骆驼案只符合 已有的约定

无论是否在课堂上或在课堂外:

变量和函数小写，如下所示:

name = "John"

def display(name):
    print("John")

如果它们多于一个单词，则用下划线“_”分隔，如下所示:

first_name = "John"

def display_first_name(first_name):
    print(first_name)

并且，如果一个变量是一个常量，它是大写的，如下所示:

FIRST_NAME = "John"

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。

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。
