python challenge 10-12

提示是a[30]的长度,首先需要找到列表a,容易发现a在文件http://www.pythonchallenge.com/pc/return/sequence.txt中,打开可以看出似乎和小时候我们说做的题目类似,属于类比的.

代码是不见了的,最终结果是5808

import Image # download the image from: http://www.pythonchallenge.com/pc/return/cave.jpg image = Image.open("cave.jpg") nsize = tuple([x / 2 for x in image.size]) odd = even = Image.new(image.mode, nsize) for x in range(image.size[0]): for y in range(image.size[1]): if x % 2 == 0 and y % 2 == 0: even.putpixel((x / 2, y / 2), image.getpixel((x, y))) elif x % 2 == 0 and y % 2 == 1: odd.putpixel((x / 2, (y - 1) / 2), image.getpixel((x, y))) elif x % 2 == 1 and y % 2 == 0: even.putpixel(((x - 1) / 2, y / 2), image.getpixel((x, y))) else: odd.putpixel(((x - 1) / 2, (y - 1) / 2), image.getpixel((x, y))) even.save("even.jpg") odd.save("odd.jpg")

在even.jpg中看到evil,这就是第12题的地址
