Proper pygame and socket player setup

Question

I am creating a 2d game where the camera follows the player. The problem occurs when a new player joins his position is not changed in the client side. The player's position is sent to the server, but as the player's position does not change, only the environment around him, and he remains in place, how can I change the position of the client and send it to the other client where it will be displayed. I'm doing this for an infinite number of players, so I need to use a "FOR" loop. And how in the "FOR" loop can I change player two, which is also the environment.

Server:
