pychallenge之三
题目还是下面一幅图配上一段话。
One small letter, surrounded by EXACTLY three big bodyguards on each of its sides.
纸面意思是一个小写字母被两边各三个大家伙包围着，其中着重加粗的EXACTLY表明只能正好是三个，
不能多也不能少。和之前一样看网页source发现一段文字，代码如下：
1 # -*- coding: utf-8 -*- 2 import re 3 4 def findwk(file): 5 """ 6 :type file: str 7 :rtype: list 8 """ 9 result = [] 10 with open(file) as f: 11 cont = f.read() 12 result = re.findall(‘[^A-Z][A-Z]{3}[a-z][A-Z]{3}[^A-Z]‘, cont) 13 14 return [word[4] for word in result] 15 16 if __name__ == ‘__main__‘: 17 print findwk(‘C:\Users\Katsu\Desktop\pych3.txt‘)
运行结果得：
C:\Python27\python.exe D:/Py/test/test.py
[‘l‘, ‘i‘, ‘n‘, ‘k‘, ‘e‘, ‘d‘, ‘l‘, ‘i‘, ‘s‘, ‘t‘]
组合下应该是linkedlist.
