使用subprocess.call（）来传递通过CMD执行命令 [英] Using subprocess.call() to pass commands to execute by cmd

问题描述

我想我的IP地址设置为一个LAN网络上的特定的。

要做到这一点，我已经使用以下尝试：

 导入子
命令='netsh接口的IPv4设置地址名称=本地连接* 4源=静态地址= 192.168.173.234掩码255.255.255.0 = =网关192.168.0.1
subprocess.call（[cmd.exe的命令]）
 

这导致的唯一事情就是开机即没有做任何事情空的cmd.exe。

此外，为了将壳=真用什么？
当我尝试使用它，蟒蛇返回一个SyntaxError

更新：如果我使用：

 命令='netsh接口的IPv4设置地址名称=本地连接* 4源=静态地址= 192.168.173.222掩码255.255.255.0 = =网关192.168.0.1
subprocess.check_call（[的Netsh.exe，指挥]）
 

的Python返回错误：

 回溯（最后最近一次调用）：
  文件D：文件路径，8号线，上述＆lt;＆模块GT;
    subprocess.check_call（[的Netsh.exe，netsh_cmd]）
  文件C：\\ Python27 \\ lib目录\\ subprocess.py，540线，在check_call
    提高CalledProcessError（RET code，CMD）
CalledProcessError：命令'['的Netsh.exe'，'netsh接口的IPv4设置地址名称=本地连接* 4源=静态地址= 192.168.173.222掩码255.255.255.0 = =网关192.168.0.1']'返回非零退出状态1
 

解决方案

如果有的Netsh.exe 某处的搜索路径（假设你是在Windows上），那么你可以通过命令字符串是：

 导入子subprocess.check_call（命令）
 

I am trying to set my IP address to a specific one on a LAN Network.

To do this i have tried using the following:

import subprocess
command='netsh interface ipv4 set address name="Local Area Connection* 4" source=static address=192.168.173.234 mask=255.255.255.0 gateway=192.168.0.1'
subprocess.call(["cmd.exe", command])

The only thing this results in is the starting up of an empty cmd.exe that isn't doing anything.

Also, what for would the shell=True be used ? When I try to use it, python returns a SyntaxError

UPDATE: If I use:

command='netsh interface ipv4 set address name="Local Area Connection* 4" source=static address=192.168.173.222 mask=255.255.255.0 gateway=192.168.0.1'
subprocess.check_call(["netsh.exe", command])

Python Returns the error:

Traceback (most recent call last):
  File "D:file path", line 8, in <module>
    subprocess.check_call(["netsh.exe", netsh_cmd])
  File "C:\Python27\lib\subprocess.py", line 540, in check_call
    raise CalledProcessError(retcode, cmd)
CalledProcessError: Command '['netsh.exe', 'netsh interface ipv4 set address name="Local Area Connection* 4" source=static address=192.168.173.222 mask=255.255.255.0 gateway=192.168.0.1']' returned non-zero exit status 1

解决方案

If there is netsh.exe somewhere in the search path (assuming you are on Windows) then you could pass the command string as is:

import subprocess

subprocess.check_call(command)
