一、创建后台进程 使用subprocess模块可以轻松创建一个后台进程。通过设置subprocess.Popen的参数,可以在不显示窗口的情况下运行Python脚本。 1、使用subprocess模块 subprocess模块提供了一个高级接口来创建和管理子进程。在Windows系统上,可以使用subprocess.STARTUPINFO来隐藏窗口。 import subprocess 创建启动信息对象 startup...

You may come across other functions like call(), check_call(), and check_output(), but these belong to the older subprocess API from Python 3.5 and earlier. Everything these three functions do can be replicated with the newer run() function. The older API is mainly still there for backw...
