Error when opening a new file using OpenStaad and python

Hi Guys

Using the NewSTAADFile function I am able to provide a location and file name for a new .STD file.

For my current case I need to read a file name from excel and then add it to the path so that I have a file location and name to use with the NewSTAADFile function.

This however does not work.

Please refer to my code and the associated error below.

I am using the Pathlib package to develop the path 

Can someone please assist?

Loc = r"C:\Users\mishal.mohanlal\Aurecon Group\GDC ERM - General\1 - Projects\000000 - NE REZ substation automation\Python automation\Staad Pro models\\"
Fname = "MM" + ".STD"
File_Path = pathlib.PurePath(Loc,Fname)
print(File_Path)
os.NewSTAADFile(File_Path,4,5)

File "c:\Users\mishal.mohanlal\Aurecon Group\GDC ERM - General\1 - Projects\000000 - NE REZ substation automation\Python automation\Substation (R2).py", line 44, in <module>
os.NewSTAADFile(File_Path,4,5)
File "<COMObject StaadPro.OpenSTAAD>", line 2, in NewSTAADFile
