What is the naming convention for Python class references
Question: 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
    

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()
    

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.


Answer: On module level the second. As a function argument, the first.
