Question

I’m creating a game with pygame and I need a map where the user can select a country by clicking on it.

Can someone help me?

Unless you find that done, I see no easy way of doing that —
You have to start by having a World map, of course — this one in Wikipedia seems a nice starting point:

–Ah, I see by your comments you have the map drawn —
Yes.if all you need is to get the color for a click, that is easier –
Pick the click coordinates with the mouse event for the click:

e = pygame.event.poll()
if e == pygame.MOUSEBUTTONDOWN:
    pos = e.pos
    # where "screen" is your variable holding the screen surface color = screen.get_at((pos))
