#任一个英文的纯文本文件，统计其中的单词出现的个数

import re

keyWord = 'word'

infilePath = r'D:\eclipse\workspace\PyStudy\words.txt'

#这段代码无法识别wordword、worder这样的情况

keysum = 0

infile = open(infilePath)

for line in infile:

keysum = keysum + len(re.findall(keyWord, line))

print keysum

#可以区分出wordword、worder这样的情况

keysum = 0

infile = open(infilePath)

for line in infile:

listword = line.split()

keysum = keysum + listword.count(keyWord)

print keysum
