Python - 類型'函數'的參數不是可迭代的錯誤

Question

因此，我應該編寫一些代碼，它需要一些文本行，通過刪除所有非關鍵詞，標點符號等來重新編譯它們，最後打印每個代碼關鍵字和它出現在哪些行上。有一次，我的代碼正在工作，看起來沒有改變任何東西，我開始得到這個錯誤，我不知道爲什麼。我並沒有想方設法讓代碼更短或什麼，我意識到這遠非理想。我只想知道如何解決這個錯誤。

編輯 - 錯誤是58行，CreateIndex中如果Word沒有在指數：

下面是代碼：

from string import * 

# Program to index sentences 

stopWords = [ "a", "i", "it", "am", "at", "on", "in", "to", "too", "very", \ 
       "of", "from", "here", "even", "the", "but", "and", "is", "my", \ 
       "them", "then", "this", "that", "than", "though", "so", "are" ] 

punctuation = [".",",",":",";","!","?","&","'"]

     text[linecount]=line 
     linecount+=1

    for line in text: 
     reworkedtext[line]="" 
     for character in range(0,len(text[line])): 
      if text[line][character] not in punctuation: 
       reworkedtext[line]=reworkedtext[line]+lower(text[line][character])

    for line in reworkedtext: 
     wordcount=0 
     reworkedtext[line]=split(reworkedtext[line]) 
     for word in range(0,len(reworkedtext[line])): 
      if reworkedtext[line][wordcount] in stopWords: 
       del(reworkedtext[line][wordcount]) 
      else: 
       wordcount+=1

      if reworkedtext[line][word][-1:] in stemming:

       linecount+=1 
      elif index[word]!=str(line): 
       index[word]=index[word]+", "+str(line) 
    for words in index: 
     print words, index[words] 

inserttext(text) 

reworktext(text) 

removestopwords(reworkedtext) 

stemwords(reworkedtext) 

createindex(reworkedtext)

好像你忘了你的initialze指數字典

def createindex(reworkedtext): #creates index and prints it 
    linecount=1 
    index = {} # <----------- add this line and see what's what :) 
    for line in reworkedtext: 
     for word in range(0,len(reworkedtext[line])): 
      if word not in index: 
       index[word]="" 
       index[word]=str(line) 
       linecount+=1 
      elif index[word]!=str(line): 
       index[word]=index[word]+", "+str(line) 
    for words in index: 
     print words, index[words]
