First, yes I'm new to this and I am obviously doing things the wrong way but will clean up the code later. right now I'm just trying to get things to function.

The Basics: I have a grid. On that grid I am placing a set of pygame rectangles at set positions with random colors. I am supposedly storing the rectangle locations to a list(tile_sprites) for later retrieval.

 for j in range(level):
      r = random.randint(0,255)
      g = random.randint(0,255)
      b = random.randint(0,255)
      color = (r,g,b)

      tile_rect = pygame.Rect(tilex, tiley, tilew, tileh)
      pygame.draw.rect(gameDisplay, color, tile_rect, 0)
      tile_sprites.append(tile_rect)
      pygame.display.update()

During the game loop, I am looking for a MOUSEBUTTONDOWN event to get the mouse position and hopefully check to see if the position collides. The code I am using was suggested for a similar example but does not work. FYI, the code is not trying to do anything at the moment except to tell me what rectangle was clicked.

 if event.type ==pygame.MOUSEBUTTONDOWN:
      for tile_rect in tile_sprites:
      pos = pygame.mouse.get_pos()
      print("the mouse pos is ",pos)
      click_idx = tile_rect.collidepoint(pygame.mouse.get_pos())
      print("Clicked on rect ",clicked)

The Results: The print function returns the correct mouse position but the click_idx is always 0 unless I click on the list[0] rectangle then I get click_idx 1.

What I need is which rectangle? Not that it was clicked, but that it was the 24th rectangle in the list so I can call back its stored position and change the color.

I have tried a few examples to no avail. Any help understanding this would be most helpful. One possible though was the rectangles are generated by a class with a Clicked method then discover which instance of the class was clicked but done know how to do that either.

EDIT:

I solved it. Used a minesweeper game tactic using numpy to pre-populate a grid array then select from the array to build tiles and detect locations.
