Question

import os
import re
import sys
sys.stdout=open('f1.txt','w')
from collections import Counter
from glob import glob

def removegarbage(text):
    text=re.sub(r'\W+',' ',text)
    text=text.lower()
    return text

folderpath='d:/induvidual-articles'
counter=Counter()


filepaths = glob(os.path.join(folderpath,'*.txt'))

num_files = len(filepaths)

with open('topics.txt','r') as filehandle:
    lines = filehandle.read()
    words = removegarbage(lines).split()
   counter.update(words)


for word, count in counter.most_common():
    probability=count//num_files
    print('{}  {} {}'.format(word,count,probability))

我得到零分割错误：浮点除零为线概率=计数// NUM_FILES

我该如何纠正它？

我需要输出格式为：单词，计数，概率

Plz帮助！

Answer 1

您的num_files变量为0。

检查folderpath='d:/induvidual-articles'是否正确（induvidual拼写错误，但原始目录可能同样拼错了。）

Answer 2

检查路径是否存在。如果是，请检查该目录是否包含至少1个.txt文件。并在if块中移动整个for循环


if num_files:
    for word, count in counter.most_common():
       ...
else:
   print "No text files found!"
