How to make Top-Down Racing game background move in opposite direction of car

Question

i am making a top down car racing game as project (i'm new to python) and i want to know how to make the track (that i have made a background) move, so that when the user's car is moving, the track is essentially moving in the opposite direction so it looks like you are progressing through the course of the circuit. (The camera is focused on the user's car)

Thanks

Just add the camera vector to the background.rect.topleft position as well:

screen.blit(background.image, background.rect.topleft+camera)
