Drawing on the Tkinter canvas

- [Instructor] Anytime the user moves the mouse…on the tkinter canvas,…the mouse move method…will get called and update the canvas…background color.…The equations on line 32 and 33…calculate new red and blue values…for the canvas color…based on the mouse's X and Y coordinates.…R and B will be integers…between zero and 255.…The math here is designed…so that when the mouse is moved…towards the top right part of the screen,…the R value will be stronger.…

When it moves towards the bottom right side…of the screen,…the blue value will be stronger.…I then take these calculated red…and blue values and use a little string…formatting on line 34 to create a hex string.…It'll be a hex value…with the red value digits.…The static value of 30…for the green value in hex code.…Then the two blue digits.…I chose to add a little bit of green…to the color mix…because I thought it made the program…look a little bit more interesting.…

The next section of code…uses the previous mouse event variable…on line 36 to determine whether or not…the mouse is being held down.…
