两个装饰器的使用，看看为什么会报错?

Question

问题遇到的现象和发生背景

问题相关代码，请勿粘贴截图

#coding=utf-8

#缓存装饰器
import time


class CacheDecorator():
    __cache={}
    def __init__(self,func):
        self.func=func

    def __call__(self, *args, **kwargs):
        #如果缓存中存在对应的方法名，则直接返回其对应返回值,提升效率
        if self.func.__name__ in CacheDecorator.__cache:
            return CacheDecorator.__cache[self.func.__name__]
        #如果缓存中不存在对应的方法名，则执行并缓存其结果
        else:
            result=self.func(*args,**kwargs)
            CacheDecorator.__cache[self.func.__name__]=result
            return result

#计时装饰器
def cost_time(func):
    def infunc(*args,**kwargs):
        start=time.time()
        result=func(args,**kwargs)
        end=time.time()
        print(f'耗时：{end-start}')
        return result
    return infunc

@cost_time
@CacheDecorator
def cost_long_time():
    '''模拟耗时较长，每次执行返回结果都一样的情况'''
    print("start!")
    time.sleep(3)
    print('end')
    return 999

if __name__ == '__main__':
    r1=cost_long_time()
    r2=cost_long_time()

    print(r1)
    print(r2)

运行结果及报错内容

C:\Users\黄佳文\AppData\Local\Microsoft\WindowsApps\python3.10.exe D:/pythonProject/pythonProject/pythonProject/pythonProject/装饰器/装饰器/05_缓存和计时装饰器练习.py

    result=self.func(*args,**kwargs)

进程已结束,退出代码1

我的解答思路和尝试过的方法

我想要达到的结果

Answer 1

是因为26行少了个 * 号吗？
另外需要涉及到函数__name__属性的话装饰器函数建议加@functools.wraps(func)
详见
