I have the following dataframe A:
score content content_preprocessed for_analysis
1 5 a aaa True
2 5 b NaN False
3 1 c ccc True
4 1 d ddd True
I need to replace content_preprocessed
column with the following new column from dataframe B:
content_preprocessed
1 aaz
3 ccf
4 ddo
which contains new values for content_preprocessed
where for_analysis
is set to True
. The values for content_preprocessed
should remain NaN
if the corresponding for_analysis
is False
.
How do I do that?
