如何删除数据框列的标题 [英] how to drop the title for data-frame columns

问题描述

我想出了一个这样的数据框，我想知道如何才能更改或删除"id"和"date"，因为它们只是索引和列的名称.

I come up with a dataframe like this, I wonder how can we change or drop the 'id' and 'date' as they are just the names for index and columns.

id               col1        col2       clo3  
date                                          
2000-01-03  55.500000         NaN        NaN  
2000-01-04  52.812500         NaN        NaN  
2000-01-05  52.750000         NaN        NaN  
2000-01-06  53.500000         NaN        NaN  
2000-01-07  53.625000         NaN        NaN  
2000-01-10  52.656250         NaN        NaN
