图片如下：

题目解析：标题odd even->奇偶 猜测PythonChallenge是要我们把图片按奇偶行、奇偶列拆开为两幅图画

解题过程：

#http://www.pythonchallenge.com/pc/return/5808.html
from PIL import Image
import time
path = r'./other/cave.jpg'
white =(255,255,255)
black = (0,0,0)

img = Image.open(path)
im = Image.new("RGBA",(350,300),(255,255,255))
img_array = im.load()

n = 0
for i in range(2,640):
    m = 0
    for j in range(2,480):
        if  ((i%2 == 0) and (j%2 ==0)):
            color = img.getpixel((i,j))
            img_array[i/2,j/2] = color
        m = m + 1
    n = n + 1

im.show()
