Executing Shell Commands with Python 实践 1、执行命令,并对输出进行处理 这里以执行systemctl status docker命令为例 import subprocess result = subprocess.run(["systemctl", 'status', 'docker'], stdout=subprocess.PIPE, text=True) s=result.stdout.split("\n") for i in s: if i.strip(): prin...
一、commands模块 1、介绍 当我们使用Python进行编码的时候,但是又想运行一些shell命令,去创建文件夹、移动文件等等操作时,我们可以使用一些Python库去执行shell命令。 commands模块就是其中的一个可执行shell命令的库,commands模块是python的内置模块,共有三个函数: getstatus(file):返回执行 ls -ld file 命令的结果(...
Python subprocess 执行shell Python’s Subprocess Module: A Comprehensive Guide to Executing Shell Commands Python的subprocess模块是一个强大的工具,能够让你在Python程序中执行shell命令。这为Python与系统命令行之间的交互提供了灵活性,尤其是在自动化任务和处理外部命令时。 什么是Subprocess模块? subprocess是Python...
