This is the simple application code which shows the present time and date. It was written in Python language. Also, in order to visualizing the app, I used the "tkinter" library. For more information , you can refer to its website and find different methods which help you to make your framework of the app. Note that I used the 3rd version of Python IDE to write this code. I also put this code in the Saakhtani which is a Persian website.
