python路径找类并获取静态字段

 Python通过路径找类并获取其中大写的静态字段

settings.py

class Foo:
    DEBUG = True
    TEST = True

xx.py

import importlib

path = "settings.Foo"

p,c = path.rsplit('.', maxsplit=1)
m = importlib.import_module(p)
cls = getattr(m, c)

# 如果找到这个类？
for key in dir(cls):
    if key.isupper():
        print(key, getattr(cls, key))
