我前面已經講過了用Matlab顯示Mandelbrot圖的方法，原理在那里也說的，鏈接地址：http://blog.csdn.net/whoispo/article/details/49557823， 這次就不講了。直接貼代碼(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 = LX1while x < LX2:y = LY1while 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 += ystepx += xstepdef count(c):z = complex(0,0)for i in range(COUNT_LIMIT):z = z*z + cif abs(z) > 2: return ireturn COUNT_LIMITCOUNT_LIMIT = 1000 LX1 = -2.0 LX2 = 2.0 LY1 = -2.0 LY2 = 2.0random_color = [] for i in range(COUNT_LIMIT):r = randint(0, 255)g = randint(0, 255)b = randint(0, 255)r = "%02x" % rg = "%02x" % gb = "%02x" % brandom_color.append("#"+r+g+b) window = Tk() window.title("曼德布羅特分形")canvas = Canvas(window, width=500, height=500, bg="white") canvas.pack()paint(LX1, LX2, LY1, LY2)window.mainloop()

python的計算速度肯定與Matlab是沒辦法比的，運行時耐心點吧。本來還綁定一個鼠標滾動放大縮小的事件，但是python計算速度太慢了，經常卡死，就放棄了。大家可以嘗試一下

如何綁定鼠標滾輪的事件，請見下一篇文章。
