You can pass a command to PowerShell and retrieve the output in your python script.

Step 1 Write a PowerShell script

    Write-Host 'Hello, World!'

save it as script.ps1

PS: This will output

    Hello, World!

Step 2 Write a python script and call your PowerShell script from there and retrieve the output

    import sys
    import subprocess

    cmd = ["PowerShell", "-ExecutionPolicy", "Unrestricted", "-File", ".\\script.ps1"]
    ec = subprocess.call(cmd)
    print("Powershell returned: {0:d}".format(ec))

This will output:

    Hello, World!
    Powershell returned: 0
