修改带参数的装饰器

一、根据用户传递的参数，动态修改装饰器的入参

二、实例：

import time,logging,random
def timeout(t):
    def outter(func):
        def inner(*args, **kwargs):
            t0 = time.time()
            res = func(*args, **kwargs)
            t1 = time.time()
            used = t1 - t0
            if used >= t:
                logging.error("{}:{}>{}".format(func.__name__, used, t))
            return res
　　　　 #修改装饰器参数方法
        def set_timeout(new_timeout):
            nonlocal t
            t = new_timeout
        inner.set_timeout = set_timeout
        return inner
    return outter


@timeout(1.5)
def f(i):
    print("in f [{}]".format(i))
    while random.randint(0, 1):
        time.sleep(0.6)


f.set_timeout(1)
for x in range(1):
    f(x)
