Python Challenge Level 1 ~ 2

Python Challenge,一个Programming Game的Site,没事玩玩。

 

Level-1:

http://www.pythonchallenge.com/pc/def/map.html

字符字典,先翻译hints。

 

#!/usr/bin/python  
  
import string  
   
""" 
Python Challenge, Level 1: 
    http://www.pythonchallenge.com/pc/def/map.html 
"""  
  
def main():  
    dictionary = {ord(string.ascii_lowercase[i]): \
        ord(string.ascii_lowercase[(i+2)%26]) for i in range(26)}  
    text = 'g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. \
bmgle gr gl zw fylb gq glcddgagclr ylb rfyr''q ufw rfgq rcvr gq qm jmle. \
sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj.'
      
    print(text.translate(dictionary))  
      
if __name__ == '__main__':  
    main()

 根据hints的释义,对url的尾字符串“map”应用该字典转义即可进入下一个level。

 

Level-2:

http://www.pythonchallenge.com/pc/def/ocr.html

 

根据hints,查看Page source code后得知是字符查找问题。

#!/usr/bin/python

import urllib.request
import re

"""
Python Challenge, Level 2:
    http://www.pythonchallenge.com/pc/def/ocr.html
"""

def main():
    url = 'http://www.pythonchallenge.com/pc/def/ocr.html'
    resp = urllib.request.urlopen(url).read().decode()
    matches = re.findall(r'<!--(.*?)-->', resp, re.DOTALL)
    result = ''.join(re.findall(r'[a-zA-Z]', matches[1]))
    
    print(result)
    
if __name__ == '__main__':
  main()
  

 得出答案:equality。替换url,顺利进入下一关。
