9 第九关
是一张图，上面有很多的黑点,查看网页源代码发现了上一关的提示：
还发现了一大串的数字
感觉又是一个使用PIL库进行图像处理的题，百度后知道要将这些点连接起来并重新画图。但是不能在原始图上修改，我们应该重新画图并进行修改。
编写代码：
from PIL import Image
def main(three):
img = Image.open('good.jpg')
# 利用img的模式和大小创建新图片
img1 = Image.new(img.mode, img.size)
# 两两为一个像素位置
positions = []
for i in range(0, len(three), 2): position = (three[i], three[i+1]) positions.append(position) for j in positions: img1.putpixel(j, (255, 255, 255)) img1.show() if __name__ == '__main__': first = [146,399,163,403,170,393,169,391,166,386,170,381,170,371,170,355,169,346,167,335,170,329,170,320,170, 310,171,301,173,290,178,289,182,287,188,286,190,286,192,291,194,296,195,305,194,307,191,312,190,316, 190,321,192,331,193,338,196,341,197,346,199,352,198,360,197,366,197,373,196,380,197,383,196,387,192, 389,191,392,190,396,189,400,194,401,201,402,208,403,213,402,216,401,219,397,219,393,216,390,215,385, 215,379,213,373,213,365,212,360,210,353,210,347,212,338,213,329,214,319,215,311,215,306,216,296,218, 290,221,283,225,282,233,284,238,287,243,290,250,291,255,294,261,293,265,291,271,291,273,289,278,287, 279,285,281,280,284,278,284,276,287,277,289,283,291,286,294,291,296,295,299,300,301,304,304,320,305, 327,306,332,307,341,306,349,303,354,301,364,301,371,297,375,292,384,291,386,302,393,324,391,333,387, 328,375,329,367,329,353,330,341,331,328,336,319,338,310,341,304,341,285,341,278,343,269,344,262,346, 259,346,251,349,259,349,264,349,273,349,280,349,288,349,295,349,298,354,293,356,286,354,279,352,268, 352,257,351,249,350,234,351,211,352,197,354,185,353,171,351,154,348,147,342,137,339,132,330,122,327, 120,314,116,304,117,293,118,284,118,281,122,275,128,265,129,257,131,244,133,239,134,228,136,221,137, 214,138,209,135,201,132,192,130,184,131,175,129,170,131,159,134,157,134,160,130,170,125,176,114,176, 102,173,103,172,108,171,111,163,115,156,116,149,117,142,116,136,115,129,115,124,115,120,115,115,117, 113,120,109,122,102,122,100,121,95,121,89,115,87,110,82,109,84,118,89,123,93,129,100,130,108,132,110, 133,110,136,107,138,105,140,95,138,86,141,79,149,77,155,81,162,90,165,97,167,99,171,109,171,107,161, 111,156,113,170,115,185,118,208,117,223,121,239,128,251,133,259,136,266,139,276,143,290,148,310,151, 332,155,348,156,353,153,366,149,379,147,394,146,399] second = [156,141,165,135,169,131,176,130,187,134,191,140,191,146,186,150,179,155,175,157,168,157,163,157,159, 157,158,164,159,175,159,181,157,191,154,197,153,205,153,210,152,212,147,215,146,218,143,220,132,220, 125,217,119,209,116,196,115,185,114,172,114,167,112,161,109,165,107,170,99,171,97,167,89,164,81,162, 77,155,81,148,87,140,96,138,105,141,110,136,111,126,113,129,118,117,128,114,137,115,146,114,155,115, 158,121,157,128,156,134,157,136,156,136] main(first+second)
得到图像：
图像上是个牛，就是英文的bull
那么第十关的url为:http://www.pythonchallenge.com/pc/return/bull.html
10 第十关
看标题好像是求len(a[30])是多少，查看网页源代码
发现一大串数据，并且发现一个txt文件
点开后发现是一个列表
百度后才知道含义
11— 表示前一个数“1”是 1 个 1；
21— 表示前一个数“11”是 由 2 个 1 组成；
1211— 表示前一个数“21”是 由 1 个 2、1 个 1 组成；
111221— 即 11 12 21 ,表示前一个数“1211”是依次由 1 个 1,1 个 2,
2 个 1组成；
那么后一组的数据就会是312211
于是编写程序求解低30位是什么元素：
def main(): # 申请2个字符串，一个为1，一个为空,a是用来存放数据的 a = '1' sub1 = '' for i in range(30): j = k = 0 while j <len(a): while k < len(a) and a[k] == a[j]: k += 1 sub1 += str(k-j) + a[j] j = k a = sub1 sub1 = '' print(len(a)) if __name__ == '__main__': main()
得到答案：
所以低10关的url是:http://www.pythonchallenge.com/pc/return/5808.html
