Python中，類型錯誤：「詮釋」對象不支持項目分配」

Question

import numpy as np 

def computeTF(wordDict, doc): 
    tfDict ={} 
    for word, count in wordDict.items(): 
     if count == 0: 
      tfDict = 0 
     else: 
      tfDict[word] = 1 + np.log2(count) 
    return tfDict 

tfDoc1 = int(computeTF(wordDict1, doc1)) 

print (tfDoc1) 

每當我嘗試運行此，我得到一個錯誤：

'TypeError: 'int' object does not support item assignment'.

Answer 1

下面的代碼將工作，不會給你錯誤了。你想分配0到字典對象，而不是增加零到字典項。

import numpy as np 

def computeTF(wordDict, doc): 
    tfDict ={} 
    for word, count in wordDict.items(): 
     if count == 0: 
      tfDict[word] = 0 #this was wrong 
     else: 
      tfDict[word] = 1 + np.log2(count) 
    return tfDict 

tfDoc1 = int(computeTF(wordDict1, doc1)) 

print (tfDoc1)
