python学习杂记--函数参数的设置

转载自  勤奋的小青蛙

其实*args指的就是不带key的可变参数, **kargs就是带key的可变参数.

示例函数：

def foo_single_arg(arg):
    print("arg = ", arg)
     
def foo_multi_args(arg, *args):
    print("arg = ", arg)
    print("*args = ", args)
     
def foo_multi_args_with_key(arg, *args, **kargs):
    print("arg = ", arg)
    print("*args = ", args)
    print("**kargs = ", kargs)

输出结果：
