如图所示代码

_                                      =   (
                                        255,
                                      lambda
                               V       ,B,c
                             :c   and Y(V*V+B,B,  c
                               -1)if(abs(V)<6)else
               (              2+c-4*abs(V)**-0.4)/i
                 )  ;v,      x=1500,1000;C=range(v*x
                  );import  struct;P=struct.pack;M,\
            j  ='<QIIHHHH',open('M.bmp','wb').write
for X in j('BM'+P(M,v*x*3+26,26,12,v,x,1,24))or C:
            i  ,Y=_;j(P('BBB',*(lambda T:(T*80+T**9
                  *i-950*T  **99,T*70-880*T**18+701*
                 T  **9     ,T*i**(1-T**45*2)))(sum(
               [              Y(0,(A%3/3.+X%v+(X/v+
                               A/3/3.-x/2)/1j)*2.5
                             /x   -2.7,i)**2 for  \
                               A       in C
                                      [:9]])
                                        /9)
                                       )   )

如图片所示

然后改名字，文件后缀为 M.bmp

然后在终端执行$python M.bmp

不要关闭终端，他会根据你的机器配置在你的主文件夹里生成m.bmp(1500x1000)图片。我只要了1分钟我的机器配置

如图所示

如图所示文件

代码我不太懂，无法解释所以然，只是看着好玩，介绍给大家。

给大家一个电梯看原文-本文介绍的

! /usr/bin/env python2

-- coding: utf-8 -

import struct

def mandelbrot(V, B, c):
if (abs(V) < 6):
return c and mandelbrot(VV+B, B, c-1)
else:
return (2+c-4abs(V)**-0.4)/255

def pixel_data_handler(T):
red = T * 80 + T ** 9 * 255 - 950 * T ** 99
green = T * 70 - 880 * T ** 18 + 701 * T ** 9
blue = T * 255 ** (1 - T ** 45 * 2)
return (red, green, blue)

width,height=1500,1000;
matrix = range(width*height);

file_write = open('M.bmp','wb').write
init_bmp_data = 'BM'+struct.pack('<QIIHHHH', widthheight3+26, 26, 12, width, height, 1, 24)
file_init_success = file_write(init_bmp_data)

for X in file_init_success or matrix:
mandelbrot_data = sum([mandelbrot(0,(index % 3 / 3. + X % width + (X / width + index / 3 / 3. - height / 2 ) / 1j ) * 2.5 / height - 2.7,255)**2 for index in matrix[:9]])/9
pixel_data = pixel_data_handler(mandelbrot_data)
binary_data = struct.pack('BBB',*pixel_data)
file_write(binary_data)

整理了整理……有请分形大神给大家讲解吧……
