统计英文文本的单词词频

import re
from collections import Counter
txt = open(\'word\').read().split()   #读取文件中内容，然后切片存储为列表
#new_txt = re.split(\'\W+\',txt)
result = Counter(txt)   #统计列表中的词频，存储为字典
print (result)
#print(result.most_common(5))   #打印出现次最多的前5个单词

word = input("Please input a word witch you want to seach:")
search = result.get(word)   #从字典中取出用户输入的key对应的value
print("The number of  \\'%s\' you input is  "  % word,search)
