[Python]用正则表达式进行word Count
# regular express to Count word
import re
import sys
word_re = re.compile(r'\W')
#line = 'How are you?'
sum = 0
#f = open("test.txt")
f = open(sys.argv[1])
for i in f.readlines():
word_count = len([word for word in word_re.split(i) if word])
sum += word_count
# print word_count
f.close()
print sum
import re
import sys
word_re = re.compile(r'\W')
#line = 'How are you?'
sum = 0
#f = open("test.txt")
f = open(sys.argv[1])
for i in f.readlines():
word_count = len([word for word in word_re.split(i) if word])
sum += word_count
# print word_count
f.close()
print sum
使用：在本目录下，新建一个test，里边写一些，英语句子。
python wordCount.py test
解释：1，正则表达式，这个可以去搜“30分钟学会正则表达式”
2，用读取的行，判断有多少个字符串，也就是word。然后每个行都累加起来。
