Python类型错误：int对象不可编辑

我不确定从何处获得此错误：

Traceback (most recent call last):
  File "C:/Users/Coscio/PycharmProjects/unigram/letterHist.py", line 78, in <module>
    main()
  File "C:/Users/Coscio/PycharmProjects/unigram/letterHist.py", line 74, in main
    bars(words)
  File "C:/Users/Coscio/PycharmProjects/unigram/letterHist.py", line 62, in bars
    init(words, lst)
  File "C:/Users/Coscio/PycharmProjects/unigram/letterHist.py", line 38, in init
    freqLegend(words,val, lst)
  File "C:/Users/Coscio/PycharmProjects/unigram/letterHist.py", line 54, in freqLegend
    freqLegend(words, val/1.5,  counter-1)
  File "C:/Users/Coscio/PycharmProjects/unigram/letterHist.py", line 53, in freqLegend
    back((max(lst)*1000)/10)
TypeError: 'int' object is not iterable

您缺少

freqLegend

的一个参数，因此您得到了意想不到的行为。您只有三个参数：

freqLegend(words, val/1.5,  counter-1)

我想你的意思是什么

freqLegend(words, val/1.5, lst,  counter-1)

您之所以会得到一个不可编辑的错误，是因为

max（）

实际上会遍历列表。由于参数

counter-1

作为参数

lst

传递给函数，因此在第二次调用

lst

时，它是一个int，无法迭代以找到最大值

freqLegend(words, val/1.5, lst,  counter-1)
