[Computer-Wiz]

Hi there, so i am starting to learn GUI in Python and i am getting better. I learned about events and coordinates. I understand most of it but of course i am still learning and i am confused.

So this program creates a circle randomly on the screen and then you can use the slider to increase or decrease the size of the circle. I also got it to print the coordinates of the circle. I need to make it so that a user can choose a circle and drag and drop to a new location and still use the slider for it.

I am new to events and using the canvas methods and i am still learning from the web. I would appreciate any help that i can get. Thanks guys you have really helped as i have began to learn python

The program code is written on a template given by my teacher so i am trying to follow that as well.
