[PyGame] Need help.. function not work i think...

[Skytarez]

Hey guys,
I'm a french beginner from python. I know all the basic python but i have a problem with pygame and class in generally..
So my game goal is :
When the game start, a window is open and a enemy is draw in, u have to click on the enemy and if u hit him(with ur mouse) then this one is desappearing and an other one is appearing, you have 30sec to click on the most enemy u can.

import sys
import pygame
from pygame.locals import *
from random import *

# Initialising
score = 0
x = int()
y = int()
size = width, height = 1280, 720
FPS = 60
timer = 0
retry = False


class Player(pygame.sprite.Sprite):
    # sprite for the enemy u have to click-on
    def __init__(self):
        # this line is required to properly create the sprite
        pygame.sprite.Sprite.__init__(self)
        # create a plain rectangle for the sprite image
        self.image = pygame.image.load("ImageSonic.png")
        self.image = pygame.transform.scale(self.image, (200, 200))
        # find the rectangle that encloses the image
        self.rect = self.image.get_rect()
        self.left = x
        self.right = x + 200
        self.top = y
        self.bottom = y + 200

    def take_aim(self):  # any code here will happen every time the game loop updates
        mx, my = pygame.mouse.get_pos()
        print(mx, my)
        aim_x, aim_y, aim_global = False, False, False
        if self.left <= mx <= self.right:
            aim_x = True
        if self.top <= my <= self.bottom:
            aim_y = True
        if aim_x or aim_y:
            aim_global = True
        return aim_global

    def random_aim(self):
        img_x = randint(100, 1180)
        img_y = randint(100, 620)
        screen.blit(self.image, (img_x, img_y))
        pygame.display.flip()


# initialize pygame and create window
pygame.init()
pygame.mixer.init()
screen = pygame.display.set_mode(size)
pygame.display.set_caption("SWAP - Fast_Click")
backGround = pygame.image.load("Image_bg_pink&blue_flou.jpg")
backGround = pygame.transform.scale(backGround, (1280, 720))
clock = pygame.time.Clock()

all_sprites = pygame.sprite.Group()
player = Player()
all_sprites.add(player)

# Game loop
running = True
while running:
    clock.tick(FPS)
    timer += 1
    if timer == 1800:
        sys.exit()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            print("Ton score est de : ", score)
            running = False
        elif event.type == MOUSEBUTTONDOWN:
            retry = Player.take_aim(player)
            if retry:
                score += 1
                all_sprites.remove(player)
                Player.random_aim(player)

    # Update
    all_sprites.update()

    # Draw / render
    screen.blit(backGround, (0, 0))
    all_sprites.draw(screen)
    # *after* drawing everything, flip the display
    pygame.display.flip()

If u don't understand something in my code, please contact me in pv and ask me.
I need to get it working in 4 days so .. (personnal game presentation)

I dont follow? You only load one image but seem to assume there will be a second?

I would suggest to to use one loop meaning there should be only one pygame.display.flip() or update() in your entire game. Also you should use pygame Rects for positions (x,y) and collision with your mouse, as that is what is there for
