How to add comment in Python

I want to share about commenting in Python, you can also use it for take a note, bug, or add a TODO list.
I find it's really helped me on maintaining the applications that I built, since after the development I always forgot the full detail of them and the comment help me call back my memories on how I did things and why I did them that way.
Hope it's useful for you please feel free to comment if you have any suggestion or questions.
