I have this code:

import pygame
from car import Car
import random
import os

Blue = (0, 28 , 234)
White = (255, 255 ,255)
Grey = (130, 130 ,131)
Black = (0, 0, 0)
Green =(50, 205, 50)

pygame.init()

screenwidth = 1100
screenheight = 700
size = (screenwidth, screenheight)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("Dragos e boss")

enemyCar = pygame.image.load("enemycar.png").convert()


all_sprites_list = pygame.sprite.Group()

playerCar = Car(Blue , 40, 50)
playerCar.rect.x = 500
playerCar.rect.y = 400

all_sprites_list.add(playerCar)

carryOn = True
clock = pygame.time.Clock()


while carryOn:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            carryOn = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_x: #if you press x the g ame closes
                carryOn = False

    keys = pygame.key.get_pressed()
    if keys[pygame.K_a]:
        playerCar.moveLeft(5)
    if keys[pygame.K_d]:
        playerCar.moveRight(5)
    if keys[pygame.K_w]:
        playerCar.moveUp(4)
    if keys[pygame.K_s]:
        playerCar.moveDown(4)
    if keys[pygame.K_z]:
        playerCar.moveUp(10)
    if keys[pygame.K_SPACE]:
        playerCar.moveDown(7)


    all_sprites_list.update()

    screen.fill(Black)

    pygame.draw.rect(screen ,Grey, (400, 0, 300,800))
    pygame.draw.line(screen, White, (550,0), (550,800), 20)

    all_sprites_list.draw(screen)

    pygame.display.flip()

    clock.tick(60)

pygame.quit()

I have a car that i can move, but it goes of the screen.
How can I make the “camera”, the view to go up with the car? Like I want to go upper in the window, with the car and be able to view it, some help to it please?
