Python-Pygame: how to move multiple full object

Question

I have drawn a snowman. But I need to make 3 of them, and not by changing their coordinates 1 by 1. I thought maybe I define 1 value in ever location and then it may be able to move it towards x axis. Current:

i= 0
import pygame, sys 
pygame.init() # Käivitame Pygame'i
ekraan = pygame.display.set_mode([800, 800]) 
pygame.display.set_caption("Snowmen") 

ekraan.fill([0, 0, 250])
def snowman():
    pygame.draw.circle(ekraan, [255, 250, 250], [400, 200], 60, 0)
    pygame.draw.circle(ekraan, [255, 250, 250], [400, 300], 75, 0)
    pygame.draw.circle(ekraan, [255, 250, 250], [400, 450], 110, 0)
    pygame.draw.circle(ekraan, [0, 0, 0], [380, 175], 12, 0)
    pygame.draw.circle(ekraan, [0, 0, 0], [420, 175], 12, 0)
    pygame.draw.rect(ekraan, [78, 71, 71], [350, 110, 100, 50], 0)
    pygame.draw.rect(ekraan, [78, 71, 71], [330, 155, 140, 5], 0)
    pygame.draw.circle(ekraan, [0,0,0], [400, 440], 9, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400, 480], 9, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400, 400], 9, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400, 360], 8, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400, 320], 8, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400, 280], 8, 0)
    pygame.draw.polygon(ekraan, [255,165,0], [[400, 205], [400, 195],[450, 200]], 0)
    pygame.draw.line(ekraan, [139, 69, 19], [450, 300], [505, 260], 8)
    pygame.draw.line(ekraan, [139, 69, 19], [500, 190], [500, 550], 3)
    pygame.draw.line(ekraan, [255, 250, 250], [498, 190], [480, 138], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [498, 190], [485, 138], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [498, 190], [490, 138], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [500, 190], [495, 140], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [500, 190], [500, 140], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [500, 190], [505, 140], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [502, 190], [510, 142], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [502, 190], [515, 142], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [502, 190], [520, 142], 2)

while i < 3:
    i+=1
    snowman(k*40)  

pygame.display.flip() # Näitame akent

running = True # Muutuja "running" väärtustamine
while running: #Tsükli käivitamine kui muutuja on tõene
    for i in pygame.event.get(): # Kuulame programmi tööd
        if i.type == pygame.QUIT: # Kui vajutame akna sulgemise nuppu
            running = False # Muudame muutuja väärtuse vääraks
pygame.quit() # Sulgeme programmi akna

Do you know how to pass a value to a function? You need to add a parameter to the function definition, for example def snowman(x):, then you'll have the k*40 value from the while loop (btw k is not defined anywhere) available inside the function and can add it to the x-positions. — skrx

You have to create function with argument - ie. offset - and use this value with all x parameters

def snowman(offset):
    pygame.draw.circle(ekraan, [255, 250, 250], [400+offset, 200], 60, 0)
    pygame.draw.circle(ekraan, [255, 250, 250], [400+offset, 300], 75, 0)
    pygame.draw.circle(ekraan, [255, 250, 250], [400+offset, 450], 110, 0)
    pygame.draw.circle(ekraan, [0, 0, 0], [380+offset, 175], 12, 0)
    pygame.draw.circle(ekraan, [0, 0, 0], [420+offset, 175], 12, 0)
    pygame.draw.rect(ekraan, [78, 71, 71], [350+offset, 110, 100, 50], 0)
    pygame.draw.rect(ekraan, [78, 71, 71], [330+offset, 155, 140, 5], 0)
    pygame.draw.circle(ekraan, [0,0,0], [400+offset, 440], 9, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400+offset, 480], 9, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400+offset, 400], 9, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400+offset, 360], 8, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400+offset, 320], 8, 0)
    pygame.draw.circle(ekraan, [0,0,0], [400+offset, 280], 8, 0)
    pygame.draw.polygon(ekraan, [255,165,0], [[400+offset, 205], [400+offset, 195],[450+offset, 200]], 0)
    pygame.draw.line(ekraan, [139, 69, 19], [450+offset, 300], [505+offset, 260], 8)
    pygame.draw.line(ekraan, [139, 69, 19], [500+offset, 190], [500+offset, 550], 3)
    pygame.draw.line(ekraan, [255, 250, 250], [498+offset, 190], [480+offset, 138], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [498+offset, 190], [485+offset, 138], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [498+offset, 190], [490+offset, 138], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [500+offset, 190], [495+offset, 140], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [500+offset, 190], [500+offset, 140], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [500+offset, 190], [505+offset, 140], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [502+offset, 190], [510+offset, 142], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [502+offset, 190], [515+offset, 142], 2)
    pygame.draw.line(ekraan, [255, 250, 250], [502+offset, 190], [520+offset, 142], 2)

And then you can run it with different values

for k in range(-1, 2):
    snowman(k*250)

    clock.tick(5) # slow down to 5 FPS so it will use less CPU power.

pygame.quit()

There is also other method.

You create Surface and draw on it and later you blit this surface in three different places.

# all import at the top !!!
import pygame
import sys 

# --- functions ---

def create_snowman():
    # create surface
    image = pygame.Surface((300, 600)).convert_alpha()

    # fill with transparent background [x,x,x,0]
    image.fill([0, 0, 0, 0])

    # draw on surface
    pygame.draw.circle(image, [255, 250, 250], [150, 200], 60, 0)
    pygame.draw.circle(image, [255, 250, 250], [150, 300], 75, 0)
    pygame.draw.circle(image, [255, 250, 250], [150, 450], 110, 0)
    pygame.draw.circle(image, [0, 0, 0], [130, 175], 12, 0)
    pygame.draw.circle(image, [0, 0, 0], [170, 175], 12, 0)
    pygame.draw.rect(image, [78, 71, 71], [100, 110, 100, 50], 0)
    pygame.draw.rect(image, [78, 71, 71], [100, 155, 140, 5], 0)
    pygame.draw.circle(image, [0,0,0], [150, 440], 9, 0)
    pygame.draw.circle(image, [0,0,0], [150, 480], 9, 0)
    pygame.draw.circle(image, [0,0,0], [150, 400], 9, 0)
    pygame.draw.circle(image, [0,0,0], [150, 360], 8, 0)
    pygame.draw.circle(image, [0,0,0], [150, 320], 8, 0)
    pygame.draw.circle(image, [0,0,0], [150, 280], 8, 0)
    pygame.draw.polygon(image, [255,165,0], [[150, 205], [150, 195],[200, 200]], 0)
    pygame.draw.line(image, [139, 69, 19], [200, 300], [255, 260], 8)
    pygame.draw.line(image, [139, 69, 19], [250, 190], [250, 550], 3)
    pygame.draw.line(image, [255, 250, 250], [248, 190], [230, 138], 2)
    pygame.draw.line(image, [255, 250, 250], [248, 190], [235, 138], 2)
    pygame.draw.line(image, [255, 250, 250], [248, 190], [240, 138], 2)
    pygame.draw.line(image, [255, 250, 250], [250, 190], [245, 140], 2)
    pygame.draw.line(image, [255, 250, 250], [250, 190], [250, 140], 2)
    pygame.draw.line(image, [255, 250, 250], [250, 190], [255, 140], 2)
    pygame.draw.line(image, [255, 250, 250], [252, 190], [260, 142], 2)
    pygame.draw.line(image, [255, 250, 250], [252, 190], [265, 142], 2)
    pygame.draw.line(image, [255, 250, 250], [252, 190], [270, 142], 2)

    return image

# --- main ---

pygame.display.set_caption("Snowmen") 

# - draw -
