1. 装饰器带有参数（比如：retry）
import time
def call_out(timeout=0):
def check_login(func):
def wrapper(*args, **kwargs):
print("-------1--------")
time.sleep(timeout)
ret = func(*args, **kwargs)
print("--------2-----------")
return ret
return wrapper
return check_login
@call_out(2)
def print_hello():
print("hello world")
return "ok"
print(print_hello())
2. 输出结果
C:UsersHuJunPycharmProjectspythonProjectvenvScriptspython.exe C:/Users/HuJun/PycharmProjects/pythonProject/daily_tesy/装饰器带有参数.py
-------1--------
