[GitHub] [arrow] rooneyp commented on issue #9160: How to filter parquet column with None using Python?

   FWIW I got it working using 'not in' operator
   `filters=[('deletionTime', 'not in', [None])]`
   
   this was done via pandas, but I think it just passes the filters down to pyarrow
   `pd.read_parquet(pq_path, engine='pyarrow',  columns=cols, storage_options=None,                                     use_nullable_dtypes=True, filters=filters)
   `
