这篇文章主要介绍了Python实现统计文本文件字数的方法,涉及Python针对文本文件读取及字符串转换、运算等相关操作技巧,需要的朋友可以参考下
本文实例讲述了Python实现统计文本文件字数的方法。分享给大家供大家参考,具体如下:
统计文本文件的字数,从当前目录下的file.txt取文件
# -*- coding: GBK -*- import string import sys reload(sys) def compareItems((w1,c1), (w2,c2)): if c1 > c2: return - 1 elif c1 == c2: return cmp(w1, w2) else: return 1 def main(): fname = "file.txt" try: text = open(fname,'r').read() text = string.lower(text) except: print "\nfile.txt is not exist!!! or There is a R/W error! " sys.exit() for ch in '!"#$%&()*+,-./:;<=>?@[\\]^_`{|}~': text = string.replace(text, ch, ' ') words = string.split(text) counts = {} for w in words: counts[w] = counts.get(w,0) + 1 n = input("\n输入要统计的top单词数:") items = counts.items() items.sort(compareItems) max = len(items) print "\n单词总计:" + str(len(words)) print "单词净个数(已去重):" + str(max) print "\n" if n > max: n = max for i in range(n): print "%-10s%5d" % items[i] if name == 'main': main()
