Python，類型錯誤：'int' 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)

每當我嘗試運行它時，都會出現錯誤：

'TypeError: 'int' 對象不支持項目分配'。

Answer 1

下面的代碼將工作，不會給你錯誤。 您試圖將 0 分配給 dict 對象，而不是向 dict 項目添加零。

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)
