This is the recommended way to run shell commands in Python compared with old-fashioned os module. This is a "real-time" method, which means you can get the shell output on the fly, compared with following "subprocess.check_output" method, which collect all output in its return value. Th...

执行shell命令的场景相当广泛。从执行文件操作到调用外部脚本,乃至处理系统监控,使用subprocess都能极大地提高工作效率。 绘制饼图示例 为了直观展示subprocess模块的应用场景,我们可以使用mermaid语法来绘制一个饼图,显示不同操作的比例。 25%35%20%20%Subprocess Usage DistributionFile OperationsExternal Script CallsSystem...
commands模块 用于执行Linuxshell命令,要获得shell命令的输出只需要在后面参数写入('命令')就可以了。 需要得到命令执行的状态则需要判断$?的值, 在Python中有一个模块commands也很容易做到以上的效果。 看一下三个函数: 1). commands.getstatusoutput(命令) ...
The Python subprocess module is used to run shell commands and manage external processes. You run a shell command using subprocess by calling subprocess.run() with the command as a list of arguments. subprocess.call(), subprocess.run(), and subprocess.Popen() differ in how they execute ...
you should consider usingsubprocess.run. For a short and quick script you might just want to use theos.system()oros.popen()functions. If you have any questions, feel free to leave them in the comments below. There are also other useful libraries that support shell commands in Python, like...
