It can be useful to combine columns as (if they were) strings.
embark_town,class,size Cherbourg,First,85 Cherbourg,Second,17 Cherbourg,Third,66 Queenstown,First,2 Queenstown,Second,3 Queenstown,Third,72 Southampton,First,127 Southampton,Second,164 Southampton,Third,353
For example it would be useful to be able to combine embark_town and class into a single column by concatenating their values together as strings.
This ought to be possible with eval, but currently eval doesn't seem to work with strings when using +.
There is an open ticket for this: https://github.com/pandas-dev/pandas/issues/47734
We could wait for that bug to be fixed, or we could consider having a combine operation.
Sometimes it would be useful to be able to combine columns and throw away the originals, other times it might be useful to keep the originals as well.
