带有隐藏窗口的跨平台子流程 [英] Cross-platform subprocess with hidden window

问题描述

我想在后台打开一个进程并与其进行交互，但是该进程在Linux和Windows中均不可见.在Windows中，您必须使用STARTUPINFO进行一些操作，而在Linux中这是无效的:

I want to open a process in the background and interact with it, but this process should be invisible in both Linux and Windows. In Windows you have to do some stuff with STARTUPINFO, while this isn't valid in Linux:

ValueError:仅Windows平台支持startupinfo

ValueError: startupinfo is only supported on Windows platforms

是否有比为每个操作系统创建单独的Popen命令更简单的方法?

Is there a simpler way than creating a separate Popen command for each OS?

if os.name == 'nt':
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    proc = subprocess.Popen(command, startupinfo=startupinfo)
if os.name == 'posix':
    proc = subprocess.Popen(command)    

推荐答案

您可以减少一行:)

startupinfo = None
if os.name == 'nt':
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
proc = subprocess.Popen(command, startupinfo=startupinfo)
