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
代码如下 | 复制代码 |
# -*- coding: GBK -*- importstring importsys reload(sys) defcompareItems((w1,c1), (w2,c2)): ifc1 > c2: return-1 elifc1==c2: returncmp(w1, w2) else: return1 defmain(): 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() forchin'!"#$%&()*+,-./:;<=>?@[\\]^_`{|}~': text=string.replace(text, ch,' ') words=string.split(text) counts={} forwinwords: 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" ifn >max: n=max foriinrange(n): print"%-10s%5d"%items[i] if__name__=='__main__': main() |
