@vyasr vyasr commented Feb 17, 2022

This PR uses the feature introduced in #10263 to remove the usage of DataFrame.columns where possible.

Currently this removes a large number of internal uses but not all of them to verify that CI does indeed fail as expected since some changes were made on #10263 after the last test of CI by reviewer request. I will convert this from a draft once I see CI fail and once all the necessary changes have been made for tests to pass.

See the failures on 0d459e7 such as this run as verification that CI will fail as expected now.

Can't spot any major issues. Do you think _set_column_names_like can be added to an overload of _from_columns_like_self in dataframe?

That's definitely a good idea for a follow-up PR, but I think it's out of scope for this one.

A quick fix to set column names in the `_from_columns_like_self` factory. Since dataframe column names are slightly more complex than simple Frame, this fix makes sure column name metadata (such as multi level names) are properly copied to the result dataframe.
