Pygame dinosaur image keeps duplicating

I'm trying to make a dinosaur game in python (like the offline dino game in chrome). I want the dino to jump when space is pressed but when I press it,not only the image of dino is duped but it also doesn't come back.

import pygame
import time

pygame.init()

displayWidth = 700
displayHeight = 350

gameDisplay = pygame.display.set_mode((displayWidth,displayHeight))
pygame.display.set_caption("Dino-Run")

black = (0,0,0)
white = (255,255,255)

clock = pygame.time.Clock()
dinoimg = pygame.image.load("dino.png")

def dino(x,y):
    gameDisplay.blit(dinoimg,(x,y))

def gameloop():
    gameExit = False
    x = (displayWidth * 0.005)
    y = (displayHeight * 0.75)
    y_change = 0

    while not gameExit:

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                gameExit = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RIGHT:
                    y_change = -5
            if event.type == pygame.KEYUP:
                if event.key == pygame.K_RIGHT:
                    y_change = 0
            
            
        y += y_change
        dino(x,y)
        pygame.display.update()
        clock.tick(60)

Could someone please tell me how can I prevent the dino to dupe each time space is pressed and for the dino to come back to the ground.

You have to override everything before drawing new things to the screen.

Add this at the beginning of your loop:

gameDisplay.fill(color)
