How to run a DOS batch file in background using Python?
Question: How to run a DOS batch file in background using Python?

I have a test.bat file in say C:\  
Now, I want to run this bat file using python in the background and then I
want to return to the python command line.

I run the batch file using `subprocess.call('path\to\test.bat')` from the
python command line. It runs the batch file in the same window as the python
command line.

If still not clear/ TL.DR-

What is happening:

    
    
    >>>subprocess.call('C:\test.bat')
    (Running test.bat. Can't use python in the same window)
    

What I want:

    
    
    >>>subprocess.call('C:\test.bat')
    (New commandline window created in the background where test.bat runs in parallel.)
    >>>
    


Answer: This seems to work for me:

    
    
    import subprocess
    
    p = subprocess.Popen(r'start cmd /c C:\test.bat', shell=True)
    
    p.wait()
    
    print 'done'
