Quote - Do you have your operating system set to show file extensions? If not it may be renaming to .py.txt instead of just .py.

hmm thought it may be that, I just took a look and the extention is not shown , so now I need to recall how to add it , I'll search for a refresher for me to remember

 

ETA: yup, just needed a refresher, of how to do it,   got it  now.
