使用鞭尾与Python子进程

Question

我正在执行下面这里提到的whittail命令WhipTail示例

whiptail --title "Check list example" --checklist 
"Choose user's permissions" 20 78 4 
"NET_OUTBOUND" "Allow connections to other hosts" ON 
"NET_INBOUND" "Allow connections from other hosts" OFF 
"LOCAL_MOUNT" "Allow mounting of local devices" OFF 
"REMOTE_MOUNT" "Allow mounting of remote devices" OFF

Python代码:

   cmd = ['whiptail', '--title', "Check list example", '--checklist', "Choose user's permissions", '20', '78', '4',
        " NET_OUTBOUND", " Allow connections to other hosts", "ON",
        " NET_INBOUND", " Allow connections from other hosts", "OFF",
        " LOCAL_MOUNT", " Allow mounting of local devices", "OFF"
        " REMOTE_MOUNT", " Allow mounting of remote devices", "OFF"]
   p = subprocess.Popen(cmd)
   p.communicate()

它不工作。你能告诉我哪里错了吗?

错误消息。鞭尾的标准错误信息。

您在行中缺少逗号:

" LOCAL_MOUNT", " Allow mounting of local devices", "OFF",

正如@BrianCain指出的那样。在将字符串转换为参数列表时，Split是您的伙伴。
