I try to use subprocess.call(["powershell.exe", ....]) but i dont know how i need to paste my script here. Thanks

Answer 1

Just like you said, using subprocess might help here. With the help of this answer:

Save your PS script in a .ps1 file on your machine and do something like:

import subprocess, sys

# An example script path = C:\\Users\\USER\\Desktop\\my_script.ps1
# Also adding the execution policy in order to avoid Security exception error

p = subprocess.Popen('powershell.exe -ExecutionPolicy RemoteSigned -file "your_script_path"', stdout=sys.stdout)

p.communicate()

Answer 2

import subprocess, sys

p = subprocess.Popen('powershell.exe -ExecutionPolicy RemoteSigned -file "PowerShell1.ps1"', stdout=sys.stdout)
p.communicate()
