如何从python脚本中启动一个批处理文件，并从中分离 [英] How to start a batch file from within a python script and detach from it

问题描述

我有一个需要启动一个的.bat 文件python脚本。在的.bat 文件将无限期运行，并且最好，永不再来。

I have a python script that needs to start a .bat file. The .bat file runs indefinitely, and, ideally, never returns.

有一个运行可执行国外没有问题或的.bat 从python脚本中，但所有的实现，我发现来看，它作为一个孩子，并等待它返回。

There's no problem running a foreign executable or .bat from within a python script, but all the implementations I've found run it as a child and wait for it to return.

我可以运行一个外部脚本，并从中分离，允许它运行欢快，并有python脚本继续运行？

Can I run an external script and detach from it, allowing it to run merrily, and have the python script continue to run?

*的编辑：* 的使用 POPEN 运行在相同的命令提示符窗口中的批处理文件 - 作为批处理文件永远不会返回时，Python应用程序我们无法继续运行。有没有办法在新的命令提示符窗口中运行的批处理文件？

* * using Popen runs the batch file in the same command prompt window - as the batch file never returns, the python app us unable to continue running. Is there a way to run a batch file in a new command prompt window?

推荐答案

您可以使用子：

import subprocess
subprocess.Popen(["mybatchfile.bat"])

这将启动批处理文件并不会等待完成。如果您想验证是否已创建过程中，你可以运行：

This starts the batch file and will not wait for to complete. If you want to verify that process is created, you can run:

p=subprocess.Popen(["mybatchfile.bat"])
if p.pid > 0:
   print "Process created with PID:", p.pid
