用python tkinter显示Mandelbrot图

我前面已经讲过了用Matlab显示Mandelbrot图的方法，原理在那里也说的，链接地址：http://blog.csdn.net/whoispo/article/details/49557823，这次就不讲了。直接贴代码(python3)：

# encoding=utf-8from tkinter import *from random import randintdef paint(LX1, LX2, LY1, LY2):    xscale = float(canvas["width"]) / (LX2 - LX1)    yscale = float(canvas["height"]) / (LY2 - LY1)    xstep = (LX2 - LX1) / (float(canvas["width"]))    ystep = (LY2 - LY1) / (float(canvas["height"]))    x = LX1    while x < LX2:        y = LY1        while y < LY2:            c = count(complex(x, y))            if c == COUNT_LIMIT:                color = "black"            else:                color = random_color[c-1]            canvas.create_rectangle((x - LX1) * xscale, (y - LY1) * yscale,                                    (x - LX1) * xscale, (y - LY1) * yscale, fill=color, outline = color, tags="pic")            y += ystep        x += xstepdef count(c):    z = complex(0,0)    for i in range(COUNT_LIMIT):        z = z*z + c        if abs(z) > 2: return i    return COUNT_LIMITCOUNT_LIMIT = 1000LX1 = -2.0LX2 = 2.0LY1 = -2.0LY2 = 2.0random_color = []for i in range(COUNT_LIMIT):    r = randint(0, 255)    g = randint(0, 255)    b = randint(0, 255)    r = "%02x" % r    g = "%02x" % g    b = "%02x" % b    random_color.append("#"+r+g+b)window = Tk()window.title("曼德布罗特分形")canvas = Canvas(window, width=500, height=500, bg="white")canvas.pack()paint(LX1, LX2, LY1, LY2)window.mainloop()

这里写图片描述

python的计算速度肯定与Matlab是没办法比的，运行时耐心点吧。本来还绑定一个鼠标滚动放大缩小的事件，但是python计算速度太慢了，经常卡死，就放弃了。大家可以尝试一下

如何绑定鼠标滚轮的事件，请见下一篇文章。
