一、subprocess模块 1、概述 subprocess 模块首先推荐使用的是它的 run 方法subprocess.run(),更高级的用法可以直接使用 Popen 接口subprocess.Popen()。 2、优点 安全性:与os.system相比,subprocess避免了shell注入攻击的风险。 灵活性:subprocess可以与子进程的stdin、stdout和stderr流进行交互。
Example: >>> >>> subprocess.getoutput('ls /bin/ls') '/bin/ls' Availability: POSIX & Windows. 在3.3.4 版更改: 添加了 Windows 支持 注释 Converting an argument sequence to a string on Windows On Windows, an args sequence is converted to a string that can be parsed using the ...
