Не могу разобраться с серверами

Сделал что-то вроде игры, и мне хочется выслать её в интернет. Слышал что надо создать сервер но не знаю как. Объясните пожалуйста. Вот код:

import pygame
pygame.init()

# игровое поле
win = pygame.display.set_mode((800, 800))
pygame.display.set_caption('Green Square (0.1)')
bg = [pygame.image.load('bg.png')]
gr = [pygame.image.load('gr.png')]
sx = 0
sy = 0
sspeed = 10


# игрок
width = 80
height = 80
x = 350
y = 350
speed = 10
prstupd = [pygame.image.load('prstup.png'),
          pygame.image.load('prstup2.png'),
          pygame.image.load('prstup3.png'),
          pygame.image.load('prstup4.png'),
          pygame.image.load('prstup5.png'),
          pygame.image.load('prstup6.png'),
          pygame.image.load('prstup7.png'),
          pygame.image.load('prstup8.png'),
          pygame.image.load('prstup9.png'),
          pygame.image.load('prstup10.png'),
          pygame.image.load('prstup11.png'),
          pygame.image.load('prstup12.png'),
          pygame.image.load('prstup13.png'),]
prrt = [pygame.image.load('prrt.png'),
          pygame.image.load('prrt2.png'),
          pygame.image.load('prrt3.png'),
          pygame.image.load('prrt4.png'),
          pygame.image.load('prrt5.png'),
          pygame.image.load('prrt6.png'),
          pygame.image.load('prrt7.png'),

    if anim == 39:

    win.blit(bg[0], (sx, sy))
    win.blit(gr[0], (sx, sy))

    if stup:
        win.blit(prstupd[anim // 3], (x, y))
        anim += 1
