using PowerShell from Python script for mounting shares

[tester_V]

I thought when I open the file with "with open..." it closes automatically...
Should I use instead of it :

    #with open('C:/Scripts/somescript/Connect-0.ps1','w') as ps :
    ps = open('C:/Scripts/somescript/Connect-0.ps1','w')
        ps.write(f"{ln1}\n")
        ps.write(f"{ln2}\n")
        ps.close()
        subprocess.call("C:/Scripts/somescript/Connect-0.ps1")

Thank you for working on weekends!
