Python 函数countwords应该删除所有停止字，但是我得到了包含停止字的字符串列表。我想知道我哪里做错了

在大多数情况下，代码看起来是正确的。在

countwords

中，需要调整

return

的缩进，使其在循环完成后返回

请尝试以下代码：

import re
filename="bibleSentences.15.txt"

def getData(filename):
  with open(filename,'r') as f:
  #converting to list where each element is an individual line of text file
  lines=[line.rstrip() for line in f]
  return lines
getData(filename)

def normalize(filename):
  #converting all letters to lowercase
  lowercase_lines=[x.lower() for x in getData(filename)]
  #strip out all non-word or tab or space characters(remove punts)
  stripped_lines=[re.sub(r"[^\w \t]+", "", x) for x in lowercase_lines]
  print(stripped_lines)
  return stripped_lines
normalize(filename)

import nltk
nltk.download('stopwords')
from nltk.corpus import stopwords
stopwords.words('english')
stopwords=set(stopwords.words('english'))

def countwords(filename):
  output_array=[]
  for sentence in normalize(filename):
    temp_list=[]
    for word in sentence.split():
      if word.lower() not in stopwords:
        temp_list.append(word)
    output_array.append(''.join(temp_list))
    print(output_array)
    return output_array
output=countwords(filename)
print(output)
countwords(filename)

输出

ss = '''
In the beginning God created the heavens and the earth. Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
And God said, "Let there be light," and there was light. God saw that the light was good, and he separated the light from the darkness. God called the light "day," and the darkness he called "night." And there was evening, and there was morning-the first day.
And God said, "Let there be a vault between the waters to separate water from water." So God made the vault and separated the water under the vault from the water above it. And it was so. God called the vault "sky." And there was evening, and there was morning-the second day.
And God said, "Let the water under the sky be gathered to one place, and let dry ground appear." And it was so. God called the dry ground "land," and the gathered waters he called "seas." And God saw that it was good.
'''.strip()

with open("bibleSentences.15.txt",'w') as f: f.write(ss)  # write test file

正文的前几行是：起初上帝创造了天地。地球是没有形状和虚空的；黑暗笼罩着深渊的表面。神的灵在水面上移动。神说，要有光，就有光。神看见光明是好的，就把光明和黑暗分开。上帝称光明为白天，称黑暗为黑夜。谢谢！这很有帮助。我想知道如何在单词之间插入空格，因为我必须计算它们在列表中的出现次数
