Python，TypeError：'int'对象不支持项目赋值“

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)

每当我尝试运行时，我都会收到错误：

以下代码可以使用，不会给您错误。您尝试将0分配给dict对象，而不是将0添加到dict项目。

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)
