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.
On module level the second:
ReferenceToClass = MyClass
As a function argument, the first:
reference_to_class = MyClass
