求Python统计英文文件内单词个数的思路

感谢微博上@刘鑫-MarsLiu的TAG每天一个小程序。你会如何实现上述题目的要求？

#!/usr/bin/env python  
# -*- coding: utf-8 -*-  

""" 
python实现任一个英文的纯文本文件，统计其中的单词出现的个数、行数、字符数 
"""  

file_name = "movie.txt"  

line_counts = 0  
word_counts = 0  
character_counts = 0  

with open(file_name, 'r') as f:  
    for line in f:  
        words = line.split()  

        line_counts += 1  
        word_counts += len(words)  
        character_counts += len(line)  

print "line_counts ", line_counts  
print "word_counts ", word_counts  
print "character_counts ", character_counts

以上代码，有哪些改进的地方？如何改进才更加pythonic？

python有1个collections库可以解决你这个问题
#!/usr/bin/python # 这么着，您看您乐意不？ import re file_name = 'test.txt' lines_count = 0 words_count = 0 chars_count = 0 words_dict = {} lines_list = [] with open(file_name, 'r') as f: for line in f: lines_count = lines_count + 1 chars_count = chars_count + len(line) match = re.findall(r'[^a-zA-Z0-9]+', line) for i in match: # 只要英文单词，删掉其他字符 line = line.replace(i, ' ') lines_list = line.split() for i in lines_list: if i not in words_dict: words_dict[i] = 1 else: words_dict[i] = words_dict[i] + 1 print 'words_count is', len(words_dict) print 'lines_count is', lines_count print 'chars_count is', chars_count for k,v in words_dict.items(): print k,v
