def fun(a, b, *args):
    print(a)

    print("="*30)
    ret = a + b
    for i in args:

print(fun(1,2,3,4))

結果：

1,2分別賦值給a,b，剩下的參數以元組的形式賦值給args

字典形式參數：

def fun(a, b, *args, **kwargs):
    
 
print(a)
    print(b)
    print(args)
    print(kwargs)

fun(1, 2, 3, 4, name = "hello", age = 20)

結果：
1
2
(3, 4)
{‘name‘: ‘hello‘, ‘age‘: 20}

傳入元組和字典：

def fun(a, b, *args, **kwargs):
    print(a)
    print(b)
    print(args)
    print(kwargs)

tup = (11,22,33)
dic = {"name":"hello", "age":20}
fun(
 
1, 2, *tup, **dic)

結果：
1
2
(11, 22, 33)
{‘name‘: ‘hello‘, ‘age‘: 20}
