python how to make a game code example

Example 1: how to make a game in python

# Set up the screen
# Python 3.7.3 chromebook
# Turtle
import turtle

# Set up the screen
turtle.Screen()

# Paddle B
paddle_b = turtle.Turtle()

# Ball

# Function

# Main game loop

# Mainloop of the game

Example 3: simple game with python

# 1 - Import library
import pygame
from pygame.locals import *

# 2 - Initialize the game
pygame.init()
width, height = 640, 480
screen=pygame.display.set_mode((width, height))

# 3 - Load images
player = pygame.image.load("resources/images/dude.png")

# 4 - keep looping through
while 1:
    # 5 - clear the screen before drawing it again
    screen.fill(0)
    # 6 - draw the screen elements
    screen.blit(player, (100,100))
    # 7 - update the screen
    pygame.display.flip()
    # 8 - loop through the events
    for event in pygame.event.get():
        # check if the event is the X button 
        if event.type==pygame.QUIT:
            # if it is quit the game
            pygame.quit() 
            exit(0)
