在Windows中使用Python打开文件后如何关闭cmd？

Question

I have a written a program using Python to open a particular file (txt) which it creates during execution. I have made a batch file to access the script using command line. The batch script is as follows:

@echo off
python F:\program\script.py %*

I have tried these two options for opening the file with Python in script.py.

subprocess.Popen(name, shell=True)

and

os.system('"'+name+'"') 

I have further made a keyboard shortcut for the batch script. The problem is I want the cmd prompt to close after the text file opens in notepad. But I have to either manually close the cmd prompt or close the notepad file which automatically closes the cmd prompt.

So my question is how can I close the cmd prompt and keep the notepad file open?

Answer 1

To execute a child program in a new process use Popen

from subprocess import Popen
Popen( [ "notepad.exe", "arg1", "arg2", "arg3" ] )
