TXT to PY suffix

If I copy he text of one of Helvetosaurs PY scripts, then paste it into a Notepad and name it, how do I change the suffix from .txt to .py so it will show up in Rhino when I ‘RunPY’?

Duh, I figured it out but am still hoping that any other hints might be possible. I just had to turn on the suffix display in Windows control panel. I love the Auto Label script, thanks Helvetosaur!
