python文本处理

某txt文件保存了一些数据，读取该文件的特定数据将数据返回为一个列表。

 

比如文本

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

95    96
92    92
92    90
95    92
90    90
100    90
95    92
90    88
95    96
100    92
95    94
100    88
100    86

92    96
90    90
90    88
92    96
100    92

 

取出里面的数字并统计

#!/usr/bin/env python

import collections
import re


fp = open(r'C:\Users\test\this.txt','r')

word = re.findall(r'\d+',fp.read().lower())
print word
print collections.Counter(word)

 结果
