        index
        
        ['col name'] for col index or [start:stop:step'] for rows index - return a Seri type
        
        loc - df.loc['row's label'] or df.loc['row's label', 'col name' ] - return seris type
        df.loc[[ row label1, row label2], [col name 1, col name 2]] - return df type
        
        [['col name1', 'col name2', ..]] return a Df type
        
        iloc - alike as loc, indexing by integer not labels
        df.iloc[row:row, col:col]
        
        filter by using df[df['col name'] == 'value']
        
        df['col name'] == 'a specified value' | produces a bool serie
        
        pd.
        
        df.head(n) - return n first rows
      - instantiation
        
        pd.Dataframe(dict)
        
        pd.read_csv('file_name.csv, chunksize=10)
        
        produces df iterator to load data in chunks
