【Python】用150行代码模拟太阳系行星运转+源码

又到每日分享Python小技巧的时候了，我真是太开心了。今天给大家分享的是模拟太阳系行星运转。听起来就很不错，效果出来的时候也是很不错的，让我们一起期待。

1、准备材料

首先我们需要准备这样一些材料

宇宙背景图

背景透明的行星图

2：编写代码

代码分块详解

导入需要的模块

###Python学习交流Q群：906715085###
import pygame  
import sys  
import math  
from pygame.locals import *

定义窗口大小、标题名称、字体设置、创建时钟

size = width, height = 1206, 780
screen = pygame.display.set_mode(size)
pygame.display.set_caption(太阳系行星运转示意图)
myfont = pygame.font.Font(None,60)
clock = pygame.time.Clock()

宇宙背景初始化

background = pygame.image.load(r 这里填背景图片本地路径 )
    screen.blit(background, (0, 0))

右侧文字及星球显示

screen.blit(pygame.transform.scale(mouth, (6, 6)), (pos_m_x, pos_m_y))

如果你很有情调的话，还可以在循环体之前加一段代码，配曲music

注：此处音乐力求达到宏伟效果，因此选的是 Victory.mp3

#添加背景音乐
pygame.mixer.music.load(\'F:/music.mp3\')
pygame.mixer.music.play(-1, 40)
pygame.mixer.music.set_volume(0.5)

最后
到这里就没有了，150行代码，不多不少刚刚好。其实还是挺多的，密密麻麻的代码先给自己点一个赞。喜欢的点赞，不懂的记得点赞收藏。下一章见。
