反射应用实例:importlib模块

#示例1
import importlib

redis = importlib.import_module("测试")
getattr(redis,"func")()
redis.func() #与上一行等价

#示例2
#给定字符串并自动执行某个函数
import importlib

path = "utils.redis.func" #给定一个函数路径
module_path,func_path = path.rsplit(".",maxsplit = 1)
module_object = importlib.import_module(module_path)

getattr(module_object,func_path)()


#示例3
#调用跨文件的类
import importlib
list = [
    "day12.redis.Foo",
    "day12.mongo.Mongo",
    "day12.mins.Fgg"
]
for path in list:
    module_path,class_name = path.rsplit(".",maxsplit=1)
    # print(module_path,class_name)
    module_object = importlib.import_module(module_path)
    redi = getattr(module_object,class_name)
    cls = redi()
    cls.func()
