pygame double jump problem

[Yegor123]

Im making a platformer game and I added the jump function but for some reason my player can do double jumps triple jumps and so on how do I fix this
here is my code

Your are setting jumped = False when the jump button is not pressed. Instead you should set jumped = False when you land.

                if tile[1].colliderect(self.rect.x, self.rect.y + dy, self.width, self.height):
                    #check if below the ground i.e. jumping
                    if self.vel_y < 0:
                        dy = tile[1].bottom - self.rect.top
                        self.vel_y = 0
                    #check if above the ground i.e. falling
                    elif self.vel_y >= 0:
                        dy = tile[1].top - self.rect.bottom
