如何使用python运行cmd Windows netsh命令?
问题内容:
我正在尝试在Windows 7上运行以下netsh命令,但返回的语法错误
Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.system("netsh interface ipv4 set interface ""Conexão de Rede sem Fio"" metric=1")
The syntax of the file name, directory name or volume label is incorrect.
1
>>>
怎么了?
问题答案:
os.system
是一个非常古老的选择,不建议使用。
相反,您应该考虑subprocess.call()
或subprocess.Popen()
。
使用方法如下:
如果您不关心输出,则:
import subprocess
...
subprocess.call('netsh interface ipv4 set interface ""Wireless Network" metric=1', shell=True)
如果您确实关心输出,则:
netshcmd=subprocess.Popen('netsh interface ipv4 set interface ""Wireless Network" metric=1', shell=True, stderr=subprocess.PIPE, stdout=subprocess.PIPE )
output, errors = netshcmd.communicate()
if errors:
print "WARNING: ", errors
else:
print "SUCCESS ", output
