python绘制烟花特定爆炸效果,python画烟花绽放出字
大家好，小编来为大家解答以下问题，python绘制烟花特定爆炸效果，python画烟花绽放出字，今天让我们一起来看看吧！
本文参考了https://blog.csdn.net/weixin_43943977/article/details/102691392博主的樱花以及https://blog.csdn.net/weixin_44786530/article/details/90311184博主的烟花
“樱花是爱情与希望的象征，代表着高雅，质朴纯洁的爱情。樱花宛如懵懂少女的，安静得在春天开放，满树的白色粉色的樱花，是对情人诉说爱情的最美语言python小作品代码。心中的某个人，就如那场寂寞的樱花雨，缓缓消失在时光的深处，留下永恒的记忆。”
“烟花过后,灿烂瞬间转为平淡。瞬息万变的烟花，花瓣如雨，纷纷坠落，似乎触手可及，却只是昙花一现。”
试着将樱花与烟花结合起来，但烟花却无法在上空绽放，后面再调整吧

注：原樱花采用Turtle，烟花采用tkinter，结合需将Turtle转化为tkinter，转化代码为：
root = tk.Tk()
cv = tk.Canvas(root, height=520, width=750)
w = turtle.TurtleScreen(cv)
t = turtle.RawTurtle(w)
以及import time与from time import time的区别。
