1.Python代码http://www.cndba.cn/hbhe0316/article/106657

def add_args_func(name, *args):
    sum = 0
    if len(args) > 0:
        for i in args:
            sum += i
        print('%s 累加和为: %d' % (name, sum))
    else:
        print('%s 没有相加的值' % name)


def main():
    add_args_func('lisi')
    add_args_func('zhang san', 1, 2)
    add_args_func('zwang wu', 1, 2, 6)

if __name__ == "__main__":
    main()

2.执行效果http://www.cndba.cn/hbhe0316/article/106657

lisi 没有相加的值
