如何通过字符串动态实例化对象和调用方法？

class xxx:    name = 'xxx'    def __init__(self, name='xxx'):        self.name = name    def hello(self):        print(f'hello {self.name}')def xxx2(name='xxx2'):    print(f'hello {name}')

import importlib# 动态导入模块xx1_module = importlib.import_module('xx1')# 动态实例化对象object = getattr(xx1_module, "xxx")()# 动态调用对象方法method = getattr(object, "hello")method()# 动态调用函数function = getattr(xx1_module, "xxx2")function()

hello xxxhello xxx2
