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。

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
