在大 pandas 数据框中替换字符串 [英] replace string in pandas dataframe

问题描述

我有一个包含多个列的数据框。我想查看一个列，如果列中的任何字符串包含@，我想用另一个字符串替换它们。我该怎么做？

解决方案

我的建议：

  df ['col'] = ['new string'if'@'in x else x for x in df ['col']] 
  

不知道哪个更快。

I have a dataframe with multiple columns. I want to look at one column and if any of the strings in the column contain @, I want to replace them with another string. How would I go about doing this?

解决方案

My suggestion:

df['col'] = ['new string' if '@' in x else x for x in df['col']]

not sure which is faster.
