Looking though the things that I need to know when I am going to use raspberry pie

Tuesday, July 25,2017
So I am looking though the coding that I need to know in by using python script for use on a Raspberry Pi , using a PiCamera that allows a Roulette croupier to track spins of the roulette wheel. I am looking though this website again looking thought the steps: https://github.com/jerseycoder/RouletteSpinTracker/blob/master/rouletteTk.py. 
I know that this is using the Tkinter which is the Python interface to the TK GU I toolkit shipped with python. so far I know that you would need to add type
                From Tkinker import*
                import tkfront
then in the end the most important part it that you should put:
                 mainloop()
For the python to go back though it again.
Using raspberry pi is  a credit-card-sized computer that plugs into your TV and a keyboard.  
For more information about what a raspberry pi is you can look at the website below:

Which you would learn how:

• To chosen or download an operating system
• Write the OS image to your SD card
• Configuring Raspbian on your pi
• Updating software
