Add details for dropping qualified columns #1340
Description
Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Prior to this PR we couldn't drop qualified columns.
Describe the solution you'd like
It would be nice to add this to the python docs. For instance we could demonstrate the ability
to drop a duplicated column by name now based on the discussion here.
It would potentially be nice to map df.find_qualified_cols to df.cols/df.col similar to how pyspark manages dropping ambiguous columns
Describe alternatives you've considered
I haven't really considered other options beyond the SQL appraoch in the full join issue discussion. This landed in core datafusion so mostly making this issue to expose it here since datafusion-python motivated it.
