I am new to coding python, and I followed everything in a 4hr video tutorial but however, I get a black screen when I run my game. I am trying to finish this game for my long-term-project in high-school. I greatly appreciate everyone who helps me with my code.

Here is my code:

 import pygame
import time
from random import randint,randrange

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

sunset = (253,72,47)

greenyellow = (184,255,0)
brightblue = (47,228,253)
orange = (255,113,0)
yellow = (255,236,0)
purple = (252,67,255)

colorChoices = [greenyellow,brightblue,orange,yellow,purple]

pygame.init()

surfaceWidth = 800
surfaceHeight = 500

imageHeight = 43
imageWidth = 100

surface = pygame.display.set_mode((surfaceWidth,surfaceHeight))
pygame.display.set_caption('Helicopter')
clock = pygame.time.Clock()

img = pygame.image.load('helicopterbettersized.png')

def score(count):
 font = pygame.font.Font('freesansbold.ttf', 20)
 text = font.render("Score: "+str(count), True, white)
 surface.blit(text, [0,0])

def blocks(x_block, y_block, block_width, block_height, gap, colorChoice):

 pygame.draw.rect(surface, colorChoice, [x_block,y_block,block_width,block_height])
 pygame.draw.rect(surface, colorChoice, [x_block,y_block_block_height+gap,block_width, surfaceHeight])


def replay_or_quit():
 for event in pygame.event.get ([pygame.KEYDOWN, pygame.KEYUP, pygame.QUIT]):
 if event.type == pygame.QUIT:
 pygame.quit()
 quit()

 elif event.type == pygame.KEYDOWN:
 continue

 return event.key

 return None

def makeTextObjs(text, font):
 textSurface = font.render(text, True, sunset)
 return textSurface, textSurface.get_rect()

def msgSurface(text):
 smallText = pygame.font.Font('freesansbold.ttf', 20)
 largeText = pygame.font.Font('freesansbold.ttf', 150)

 titleTextSurf, titleTextRect = makeTextObjs(text, largeText)
 titleTextRect.center = surfaceWidth / 2, surfaceHeight / 2
 surface.blit(titleTextSurf, titleTextRect)

 typTextSurf, typTextRect = makeTextObjs('Press any key to continue', smallText)
 typTextRect.center = surfaceWidth / 2, ((surfaceHeight / 2) + 100)
 surface.blit(typTextSurf, typTextRect)

 pygame.display.update()
 time.sleep(1)
