[PyGame] I found a way to generate sprites without .blit. Is it effecient?

You can also use strings.

import pygame

def create_sprite(color, pixel_size, data):
    size = len(data[0]) * pixel_size, len(data) * pixel_size
    surface = pygame.Surface(size, pygame.SRCALPHA)
    surface.fill((0, 0, 0, 0))
    for y, row in enumerate(data):
        for x, value in enumerate(row):
            if value == "x":
                surface.fill(color, (x * pixel_size, y * pixel_size, pixel_size, pixel_size))

    return surface

def main():
    pygame.init()
    # basic pygame setup
    pygame.display.set_caption("Sprite Creation Example")
    surface = pygame.display.set_mode((500, 500))
    rect = surface.get_rect()
    clock = pygame.time.Clock()
    delta = 0
    fps = 60

    squid = create_sprite(pygame.Color("white"), 10,
        ("   xx   ",
         "  xxxx  ",
         " xxxxxx ",
         "xx xx xx",
         "xxxxxxxx",
         "  x  x  ",
         " x xx x ",
         "x x  x x"))

    squid_rect = squid.get_rect(center=rect.center)
    squid_vector = pygame.Vector2(squid_rect.topleft)
    speed = 0.05

    # main loop
    running = True
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False

        key = pygame.key.get_pressed()
        if key[pygame.K_UP]:
            squid_vector.y -= speed * delta
        if key[pygame.K_DOWN]:
            squid_vector.y += speed * delta
        if key[pygame.K_RIGHT]:
            squid_vector.x += speed * delta
        if key[pygame.K_LEFT]:
            squid_vector.x -= speed * delta

        squid_rect.topleft = squid_vector

        # Draw
        surface.fill(pygame.Color('black'))
        surface.blit(squid, squid_rect)
        pygame.display.flip()
        delta = clock.tick(fps)

if __name__ == "__main__":
    main()
