i am making a simulator and i need every pixel of the pygame screen to be an int so i have some data like a pixel may be like 10000000 the first digit is the indicator that the pixel is loaded the second is if the pixel is explored and goes on. while creating the main city pixels i need to let the pixel know that it is occupied so i want to update the in to 11011010 while i do that it throws this error

Here the code

There could be some changes done to your code to shorten it using a color table (as probably intended from the begin, but not implemented). Below the entire code with the full range of changes implementing animation and a limitation of displayed frames in order to prevent the CPU from overheating in a not paused while loop. Check it out, adjust the screen size to your desktop size and enjoy the animation (adjust the density of colored points with REPS, frame rate with FPS) in FULLSCREEN mode:
