煙花 第1步：模塊導(dǎo)入 import pygame, math, time, random, osfrom sys import exit
第2步：定義相關(guān)初始 win（窗口的w=寬，h=高） WIN_W = 2200WIN_H = 1300
定義時(shí)間、顯示、頻率 t1 = 0.18 #時(shí)間流速show_n = 0show_frequency = 0.0015 #煙花綻放頻率，數(shù)值越大頻率越高
煙花顏色列表，下面隨機(jī)抽出 color_list = [ [255, 50, 50], [50, 255, 50], [50, 50, 255], [255, 255, 50], [255, 50, 255], [50, 255, 255], [255, 255, 255] ]
初始化pygame和音樂(lè)mixer pygame.init()pygame.mixer.init()
創(chuàng)建一個(gè)窗口,pygame.RESIZABLE窗口大小可調(diào)節(jié)和標(biāo)題 screen = pygame.display.set_mode((WIN_W, WIN_H),pygame.RESIZABLE, 32)pygame.display.set_caption('五彩煙花大放送')
背景音樂(lè)，可自定義 sound_wav = pygame.mixer.music.load('123.mp3')pygame.mixer.music.play()
