class 동적으로 import하기

class가 있는 module위치를 import 한 후 class_name으로 class를 호출한다.

import importlib
module = importlib.import_module(module_name)
class = getattr(module, class_name)

 

main.py

import importlib

def call_by_classname():
    class_path = "callable.Callable"
    path = class_path.split(".")
    class_name = path[-1]
    module_path = ".".join(path[:-1])
    module = importlib.import_module(module_path)
    call = getattr(module, class_name)().run()

call_by_classname()

 

callable.py

class Callable:
    def __init__(self):
        pass

    def run(self):
        print("hello")
