Python 是一種通用編程語言，可以用于開發各種應用程序。其中一個有趣的項目是用 Python 編寫一個小球彈彈彈游戲。該游戲要求用戶幫助小球通過反彈避免撞到四周的墻壁。

import pygame
# Initialize Pygame
pygame.init()
# Set up screen size
screen_width = 500
screen_height = 500
screen = pygame.display.set_mode((screen_width, screen_height))
# Set up ball
ball_radius = 20
ball_color = (255, 255, 255)
ball_pos = [screen_width//2, screen_height//2]
ball_speed = [1, 1]
# Run game loop
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
# Move ball
ball_pos[0] += ball_speed[0]
ball_pos[1] += ball_speed[1]
# Bounce ball off walls
if ball_pos[0]< ball_radius or ball_pos[0] >screen_width - ball_radius:
ball_speed[0] = -ball_speed[0]
if ball_pos[1]< ball_radius or ball_pos[1] >screen_height - ball_radius:
ball_speed[1] = -ball_speed[1]
# Draw ball on screen
screen.fill((0, 0, 0))
pygame.draw.circle(screen, ball_color, ball_pos, ball_radius)
pygame.display.flip()
# Quit Pygame
pygame.quit()

在這段代碼中，我們使用 Pygame 庫創建一個屏幕并設置一個小球。該小球在屏幕上移動，并通過墻壁反彈。當用戶關閉屏幕時，游戲循環結束并退出 Pygame。這是一個簡單而有趣的游戲項目，可以通過添加更多功能和玩家交互來進行擴展。
