In Python IDE, while we save the script, it will prompt the save Dialog. If we specify the filename as "Test". Then file will be saved without extension as "Test" and not "Test.py".
Is it possible to save the script with .py extension automatically (as Test.py)?
Unfortunately, IDLE doesn't and can't add the .py extension automatically; you will just have to get into the habit of adding it yourself, or use another IDE like Eclipse or Komodo that will do it for you.
