sprite cant jump when on platform

I am making a platform game, so platforms are obviously important, but I have arrived at a problem. I am trying to make my character jump on my platform. I have managed to make it jump onto the platform and move left and right and fall off but once I am on the platform I can't jump. There is also another problem where if the sprite touches the bottom of the platform it will float up until its on top which it would ideally just be prevented from getting through. This issue isn't as important.

def level1():      global running, jumping1, neg1      global x1, y1 , x2, y2, xChange1, yChange1, xChange2, yChange2, jump1, jump2, jumping1, jumping2, isJump              while running:          clock.tick(FPS)                    for event in pygame.event.get():              if event.type == pygame.QUIT:                  running = False              if event.type == pygame.KEYDOWN:                  if event.key == pygame.K_LEFT:                      xChange1 = -5                  if event.key == pygame.K_RIGHT:                      xChange1 = 5                  if event.key == pygame.K_UP:                      if not jumping1:                              jumping1 = True              if event.type == pygame.KEYUP:                  if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:                      xChange1 = 0                  if event.type == pygame.KEYDOWN:                  if event.key == pygame.K_a:                      xChange2 = -5                  elif event.key == pygame.K_d:                      xChange2 = 5                  elif event.key == pygame.K_w:                      if not jumping2:                          jumping2 = True              if event.type == pygame.KEYUP:                  if event.key == pygame.K_a or event.key == pygame.K_d:                      xChange2 = 0                            if jumping1:              if jump1 >= -jumpCount:                  neg1 = 1                  if jump1 <0:                      neg1 = -1                  y1 -= (jump1 **2) * 0.5 * neg1                  jump1 -= 1              else:                  jump1 = jumpCount                  jumping1 = False            if jumping2:              if jump2 >= -jumpCount:                  neg1 = 1                  if jump2 <0:                      neg1 = -1                  y2 -= (jump2 **2) * 0.5 * neg1                  jump2 -= 1              else:                  jump2 = jumpCount                  jumping2 = False              x1 += xChange1          x2 += xChange2          y1 += yChange1          y2 += yChange2            p1Rect = player1_image.get_rect(x=x1 + xChange1,y=y1 + yChange1)            if p1Rect.colliderect(Level1Platform1Rect):              print('player 1 platform 1 collision')              jump1 = 0              y1 += -5                     if not p1Rect.colliderect(Level1Platform1Rect):              y1 += 5                      screen.blit(game_image,(0,0))          character1(x1,y1)          character2(x2,y2)          gameFloor(fx,fy)          gameFloor2(0,100)          gameFloor2(0,500)          gameFloor2(350,300)              if x1 < 0:              x1 = 0          if x1 > WIDTH - Char1WIDTH:              x1 = WIDTH - Char1WIDTH            if y1 < 0:              y1 = 0          if y1 > HEIGHT - Char1HEIGHT :              y1 = HEIGHT - Char1HEIGHT            if x2 < 0:              x2 = 0          if x2 > WIDTH - Char2WIDTH:              x2 = WIDTH - Char2WIDTH            if y2 < 0:              y2 = 0          if y2 > HEIGHT - Char2HEIGHT:              y2 = HEIGHT - Char2HEIGHT                                             pygame.display.flip()
