python - 在Python的列表中使用min函数获取AttributeError

Question

源代码

data[data['current_balance'] == ['current_balance'].min()]

错误

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-17-7c38f54b69b2> in <module>
      1 #observation with minimum current balance
----> 2 data[data['current_balance'] == ['current_balance'].min()]

AttributeError: 'list' object has no attribute 'min'

Answer 1

您正在列表min()上使用['current_balance']，您的代码应如下所示:

data[data['current_balance'] == min(data['current_balance'])]
OR
data[data['current_balance'] == data['current_balance'].min()]

我不知道data['current_balance']是什么类型的对象。但是上述方法之一可以消除您遇到的错误。
