以编程方式确定函数所需的参数量 - Python

def func(*args):
    for arg in args:
        print(arg)

func(1, 2, 3, 4)

1
2
3
4

def func(**kwargs):
    for key, value in kwargs.items():
        print(key, value)

func(a=1, b=2, c=3)

a 1
b 2
c 3

def func(*args, **kwargs):
    print("args:", args)
    print("kwargs:", kwargs)

func(1, 2, 3, a=4, b=5, c=6)

args: (1, 2, 3)
kwargs: {'a': 4, 'b': 5, 'c': 6}
