Python函数中不定长参数的写法

def fun(a, b, *args):
 print(a)
 print(b)
 print(args)
 print("="*30)
 ret = a + b
 for i in args:
  ret += i
 return ret
print(fun(1,2,3,4))

def fun(a, b, *args, **kwargs):
 print(a)
 print(b)
 print(args)
 print(kwargs)
fun(1, 2, 3, 4, name = "hello", age = 20)

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)
