统计以每个字母开头的单词
我的第一个python程序，纪念一下。字典文件选的是ubuntu系统中美式英语和英式英语常用单词列表（/usr/share/dict/american-english和/usr/share/dict/british-english）。结果显示s开头的单词最多，11000多，c开头的也不少，接近10000个。
- #!/usr/bin/env python
- # -*- coding: utf-8 -*-
- def getCountList(path):
- dict = {}
- sum = 0
- file = open(path,'r')
- wordList = file.readlines()
- for word in wordList:
- letter = word[0].lower()
- if(96 < ord(letter) < 123 ):
- if(dict.has_key(letter)):
- dict[letter] += 1
- else:
- dict[letter] = 1
- sum += 1
- else:
- print '该单词不能识别 %s' % word
- dict['*'] = sum
- return sorted(dict.items(), key=lambda x:x[1], reverse=True)
- def main():
- americanList = getCountList('/usr/share/dict/american-english')
- britishList = getCountList('/usr/share/dict/british-english')
- print ' American British '
- print '====================='
- for i in range(0,27):
- print ' %s %6d | %s %6d' %(americanList[i][0], americanList[i][1], britishList[i][0], britishList[i][1])
- if __name__ == '__main__':
- main()
输出结果
American British
