1、首先，函數是對象
2、

def fun1(*n):res=mysum(n)print(res)def mysum(n:list):if not n:return 0else:return n[0]+mysum(n[1:])def mys(name:'',degree:int,inc:int)->int:print(name,":",degree,"=>",inc)fun1(12,13,14,15,16,99,88) fun2=fun1 print(fun1.__name__) print(fun2.__name__) mys("張三",12,32) print(dir(fun2)) print(mysum.__annotations__) print(mys.__annotations__) __name__ 函數名 dir(fun2) 函數屬性名列表 __annotations__ 函數注釋 257 fun1 fun1 張三 : 12 => 32 ['__annotations__', '__call__', '__class__', '__closure__', '__code__', '__defaults__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__get__', '__getattribute__', '__globals__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__kwdefaults__', '__le__', '__lt__', '__module__', '__name__', '__ne__', '__new__', '__qualname__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__'] {'n': <class 'list'>} {'name': '', 'degree': <class 'int'>, 'inc': <class 'int'>, 'return': <class 'int'>}

自定義函數屬性runcount
