通过读取配置文件执行相应的方法
文件路径
# settings.py 模块是用来配置相应的路径 setting_list = [ 'test1.message.email.Email', 'test1.message.message.Message' ]
#run.py 模块是调用send()方法 from test1.message import send def fun(msg): send(msg) msg = "hello world" fun(msg)
# __init__.py 模块加载send()方法时,从settings中找到配置文件 #加载模块,创建对象,执行配置文件中所对应的方法 import importlib from settings import setting_list
def send(msg): for path in setting_list: m,c = path.rsplit('.',1) md = importlib.import_module(m) cls = getattr(md,c)() cls.send(msg)
# email.py 执行email发送 class Email(): def send(self,msg): print('email'+msg)
