Python - Saving A File Being Edited In Gnu Nano 2.2.4

I'm very new to programming and playing around with a Raspberry Pi and following tutorials on Youtube. I have opened a file in GNU Nano 2.2.6 e.g: nano my_File.py and changed some

Solution 1:

If you press Ctrl-X, for exit, it will ask you whether you want to save the file. Ctrl-O is for saving file without exiting the editor.

Ctrl-G is for help on key combinations.
