The code doesn't work, the error in the description used only the pygame library, help me?

Question

Python

import pygame

pygame.init()
win = pygame.display.set_mode((1000, 700))

pygame.display.set_caption("GAME")


x = 500
y = 620
width = 50
height = 65
speed = 10

isJump = False
jumpCount = 10


run = True
while run:
  pygame.time.delay(50)

  for event in pygame.event.get():
    if event.type == pygame.QUIT:
      run = False

  keys = pygame.key.get_pressed()
  if keys[pygame.K_LEFT] and x > 5:
    x -= speed
  if keys[pygame.K_RIGHT] and x < 1000 - width - 5:
    x += speed
  if not(isJump):
    if keys[pygame.K_SPACE]:
      isJump = True
  else:
    if jumpCount >= -10:
      if jumpCount < 0:
        y += (jumpCount ** 2) / 2
      else:
        y -= (jumpCount ** 2) / 2
      jumpCount -= 1
    else:
      isJump = False
      JumpCount = 10
  win.fill((0,0,0))	
  pygame.draw.rect(win, (128, 0, 128), (x, y, width, height))
  pygame.display.update()

pygame.quit()
