如何为每个列名添加后缀(或前缀)? [英] How to add a suffix (or prefix) to each column name?

问题描述

我想在每个列名中添加_x后缀，如下所示:

I want to add _x suffix to each column name like so:

featuresA = myPandasDataFrame.columns.values + '_x'

我该怎么做?另外，如果我想添加x_作为后缀，解决方案将如何更改?

How do I do this? Additionally, if I wanted to add x_ as a suffix, how would the solution change?

推荐答案

您可以使用list理解:

df.columns = [str(col) + '_x' for col in df.columns]

还有一些内置方法，例如 和 .add_prefix() 如另一个答案中所述.

There are also built-in methods like .add_suffix() and .add_prefix() as mentioned in another answer.
