Pygame code crashing Python

Any time I run a Python code game from Jupyter it opens in pygame and crashes leaving me with the spinning wheel of death and no choice but to force quit Python app. I’m self teaching and very much at the beginner stage. For example, this code below which is a snake game copied from a tutorial simply won’t run even though I’m pretty sure it’s got no typos… any help would be seriously appreciated!

dis_width = 600
dis_height = 400

dis = pygame.display.set_mode((dis_width, dis_height))
pygame.display.set_caption(‘Snake Game’)

clock = pygame.time.Clock()

snake_block = 10
snake_speed = 15

font_style = pygame.font.SysFont(‘bahnschrift’, 25)
score_font = pygame.font.SysFont(‘comicsansms’, 35)

def Your_score(score):
value = score_font.render('Your Score: ’ + str(score), True, yellow)
dis.blit(value, [0, 0])

def our_snake(snake_block, snake_list):
for x in snake_list:
pygame.draw.rect(dis, black, [x[0], x[1], snake_block, snake_block])

def message(msg, color):
    mesg = font_style.render(msg, True, color)
    dis.blit(msg, [dis_width / 6, dis_height / 3])
