我不知道为什么选项4和5不会工作。它只是在我做的菜单中一次又一次地循环。有人可以帮助我，因为我很难搞清楚它为什么不起作用。如果有人弄明白，我会非常感激，因为我尝试了4个多小时重新安排代码才能让它工作

Answer 1

您在delete_ip和ping_ip之后忘记了括号（）。

Answer 2

你没有调用函数：

elif (choice =='4'):
    delete_ip
elif (choice =='5'):
    ping_ip

尝试：

elif (choice =='4'):
    delete_ip()
elif (choice =='5'):
    ping_ip()

我不知道为什么我的删除和ping不会工作。蟒
