Python类引用的命名约定是什么 [英] What is the naming convention for Python class references

问题描述

引用Python中的类的变量的命名约定是什么?

What is the naming convention for a variable referencing a class in Python?

class MyClass(object):
    pass

# which one is correct?
reference_to_class = MyClass

# or
ReferenceToClass = MyClass

这是另一个与我的情况类似的示例:

Here is another example that resembles my situation:

# cars.py
class Car(object):
    pass

class Sedan(Car):
    pass

class Coupe(Car):
    pass

class StatonWagon(Car):
    pass

class Van(Car):
    pass

def get_car_class(slug, config):
    return config.get(slug)

# config.py
CONFIG = {
    'ford-mustang': Coupe,
    'buick-riviera': Coupe,
    'chevrolet-caprice': Sedan,
    'chevy-wan' Van:
    'ford-econoline': Van
}

# main.py
from config.py import CONFIG
from cars import get_car_class

MyCarClass = get_car_class('buick-riviera')

my_car = MyCarClass()

我更喜欢ReferenceToClass，因为每个新接触代码的人都知道这是一个类，而不是实例.但是正如@poplitea所写，文献参考会很棒.

I would prefer ReferenceToClass, that everybody new to the code knows it's a class and not an instance. But as @poplitea wrote, literature reference would be great.

推荐答案

第二个模块级别:

ReferenceToClass = MyClass

作为函数参数，第一个:

As a function argument, the first:

reference_to_class = MyClass
