3-06函数-非固定参数

函数—非固定参数(1)   带*的参数只能放在后面

def send_msg(msg,*args)

    for u in args:

   print(msg,args)

如果参数中出现*，则传递的参数就可以不再是固定个数。传过来的所有参数打包成元组

方式一：

send_msg("报警信息"，“Jack”,"Tom","Susan ")

方式二：

      send_msg("报警信息"，*[“Jack”,"Tom","Susan "])

 

函数—非固定参数(2)

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

func("Apple",23,"tesla","500W")

运行结果：Apple (23, 'tesla', '500W') {}

func("Apple",23,"tesla","500W",addr="山东",num=123)

运行结果：Apple (23, 'tesla', '500W') {'addr': '山东', 'num': 123}

d={"degree":"primary school"}
func("Amy",d)

运行结果：Amy ({'degree': 'primary school'},) {}

如想要将d，直接传到字典参数中，怎么做？

d={"degree":"primary school"}
func("Amy",**d)

运行结果：Amy () {'degree': 'primary school'}
