数据框对象没有属性 [英] Data-frame Object has no Attribute

问题描述

我知道以前曾问过这种问题，我已经检查了所有答案，并且尝试过几次，但徒劳无功. 实际上，我使用Pandas来调用Dataframe.我已经上传了一个csv.file.

I know that this kind of question was asked before and I've checked all the answers and I have tried several times to find a solution but in vain. In fact I call a Dataframe using Pandas. I've uploaded a csv.file.

当我键入data.Country和data.Year时，我得到第一列，并显示第二列.但是，当我键入data.Number时，每次都会出现此错误:

When I type data.Country and data.Year, I get the 1st Column and the second one displayed. However when I type data.Number, everytime it gives me this error:

AttributeError:"DataFrame"对象没有属性"Number".

AttributeError: 'DataFrame' object has no attribute 'Number'.

推荐答案

使用data.columns

它应该打印出这样的内容

It should print something like this

Index([u'regiment', u'company',  u'name',u'postTestScore'], dtype='object')

检查隐藏的空格.然后可以使用

Check for hidden white spaces..Then you can rename with

data = data.rename(columns={'Number ': 'Number'})
