How to 1.open cmd.exe 2.send commands to the open cmd window from python script

Hi I hope you are having a good day.

How does one open the command prompt
and then send commands to the already open console window from a python script.

I have already tried the following
+subprocess.Popen([‘cmd’,‘some command’],cwd=…)
The above line only opens the cmd window but does not pass the second command in the list to cmd.exe.
os.exec produces the same results as subprocess.Popen(…)

os = windows 7

Thanks any or solutions will be greatly appreciated

You need to create the Popen process and specify that it will read stdin from a Pipe in the Python process. You can then send whatever you want using the communicate() method.

import subprocess

process = subprocess.Popen('cmd', stdin=subprocess.PIPE)

# Note that you have to send bytes by putting a <b> before the string
process.communicate(b'echo Hello World!
')

Side note: This question doesn’t really have anything to do with the BGE and would be more suited to some other programming forum or help site such as Stack Overflow.

Thanks
The code does not accomplish the task the cmd window closes before I can see the result .
using os.system(“pause”) displayed a blank window, the trick with the input function was also fruitless
