对python执行linux命令的两种方法感兴趣的小伙伴，下面一起跟随编程之家 jb51.cc的小编两巴掌来看看吧！

python执行linux命令有两种方法：

在此以Linux常用的ls命令为例：

方法一：使用os模块

shell# python

>> import os

>> os.system('ls -l')

# End www.jb51.cc

执行结果：

drwxr-xr-x 2 root root 4096 2012-03-12 bin

drwxr-xr-x 4 root root 1024 2011-10-31 boot

drwxr-xr-x 6 root root 4096 2011-11-22 data

drwxr-xr-x 12 root root 3620 01-11 16:01 dev

drwxr-xr-x 93 root root 12288 01-17 04:02 etc

drwxr-xr-x 16 root root 4096 10-18 18:53 home

drwxr-xr-x 11 root root 4096 2012-03-12 lib

drwxr-xr-x 8 root root 4096 2012-01-20 lib64

drwx------ 2 root root 16384 2011-10-31 lost+found

drwxr-xr-x 2 root root 4096 2010-01-27 media

drwxr-xr-x 2 root root 0 01-11 16:00 misc

drwxr-xr-x 2 root root 4096 2011-12-02 mnt

drwxr-xr-x 2 root root 0 01-11 16:00 net

drwxr-xr-x 12 root root 4096 2011-11-22 new

drwxr-xr-x 2 root root 4096 2010-01-27 opt

dr-xr-xr-x 168 root root 0 01-11 15:59 proc

drwxr-x--- 6 root root 4096 11-06 11:30 root

drwxr-xr-x 2 root root 12288 2012-03-31 sbin

drwxr-xr-x 2 root root 4096 2011-10-31 selinux

drwxr-xr-x 2 root root 4096 2010-01-27 srv

drwxr-xr-x 11 root root 0 01-11 15:59 sys

drwxrwxrwt 4 root root 20480 01-18 04:02 tmp

drwxr-xr-x 16 root root 4096 07-25 16:34 usr

drwxr-xr-x 21 root root 4096 2011-11-02 var

# End www.jb51.cc

方法二：使用subprocess模块

shell# python

>> import subprocess

>> subprocess.call('ls -l'.split())

# End www.jb51.cc

执行结果是相同的。

ps：开发中最常用的方法是os模块方法。
