Python脚本在终端中执行命令 [英] Python Script execute commands in Terminal

问题描述

我不久前在某处读到过这个，但似乎找不到.我试图找到一个命令，该命令将在终端中执行命令，然后输出结果.

I read this somewhere a while ago but cant seem to find it. I am trying to find a command that will execute commands in the terminal and then output the result.

例如:脚本将是:

command 'ls -l'

它会输出在终端中运行该命令的结果

It will out the result of running that command in the terminal

推荐答案

有几种方法可以做到这一点:

There are several ways to do this:

一个简单的方法是使用 os 模块:

A simple way is using the os module:

import os
os.system("ls -l")

使用 subprocess 模块可以实现更复杂的事情:例如:

More complex things can be achieved with the subprocess module: for example:

import subprocess
test = subprocess.Popen(["ping","-W","2","-c", "1", "192.168.1.70"], stdout=subprocess.PIPE)
output = test.communicate()[0]
