获取IndexError:只有整数,切片(`:`),省略号(`...`),numpy.newaxis(`None`)和整数或布尔数组才是有效索引

运行此函数时出现此索引错误。此函数查找城市邮政编码的平均租金价格。我有一本名为city的城市字典,其中邮政编码为键,城市名称为值。有些城市有多个邮政编码,而arrRent是一个包含城市房屋租金清单的数组,我想找到平均租金价格。

def meanPrice(self, city):
    total = 0
    cityLoc = 0
    for keys, cities in self.city.items():
        if self.city[keys] == city:
            for i in self.arrRent[cityLoc]:
                total += int(self.arrRent[cityLoc][i])
            mean = total / i
            print(total / i)
        else:
            cityLoc += 1

这是字典的摘录:

{'95129': 'San Jose'}
{'95128': 'San Jose'}
{'95054': 'Santa Clara'}
{'95051': 'Santa Clara'}
{'95050': 'Santa Clara'}

这是数组的一个片段:

[['2659' '2623.5' '2749.5' '2826.5' '2775' '2795' '2810' '2845' '2827'
  '2847' '2854' '2897.5' '2905' '2925' '2902.5' '2869.5']

['3342.5' '3386' '3385' '3353' '3300' '3190' '3087.5' '3092' '3170'
  '3225' '3340' '3315' '3396' '3470' '3480' '3380']

['2996' '2989' '2953' '2950' '2884.5' '2829' '2785' '2908' '2850' '2761'

 ['2804.5' '2850.5' '2850' '2850' '2867' '2940' '2905' '2945' '2938'
  '2860' '2884' '2946' '2938' '2986.5' '2931.5' '3032.5']

 ['2800' '3074' '2950' '2850' '2850' '2875' '2757' '2716' '2738.5' '2696'
  '2809' '2891' '3000' '2960' '2950' '2831']]

答案 0 :(得分:0)

我看到2个问题:

  1. 在列表中的“ arrRent”中出现:应该是包含租金的列表的列表。但是在列表中,不同的租金没有用逗号分隔:
      [['2659' '2623.5' '2749.5' '2826.5' '2775' '2795' '2810' '2845' '2827'
          '2847' '2854' '2897.5' '2905' '2925' '2902.5' '2869.5']

       ['3342.5' '3386' '3385' '3353' '3300' .......
  1. 您的代码问题似乎在此代码块中。我是这里的实际租金,而不是指数:
    for i in self.arrRent[cityLoc]:
        total += int(self.arrRent[cityLoc][i])

将其更改为此:

for i in self.arrRent[cityLoc]:
    total += int(i)
