# pandas.DataFrame.to_dict

DataFrame.to_dict(orient='dict', *, into=<class 'dict'>, index=True)

  Convert the DataFrame to a dictionary.

  The type of the key-value pairs can be customized with the parameters (see below).

  Parameters:
    orientstr {‘dict’, ‘list’, ‘series’, ‘split’, ‘tight’, ‘records’, ‘index’}

      Determines the type of the values of the dictionary.

      - ‘dict’ (default) : dict like {column -> {index -> value}}

      - ‘list’ : dict like {column -> [values]}

      - ‘series’ : dict like {column -> Series(values)}

      - ‘split’ : dict like {‘index’ -> [index], ‘columns’ -> [columns], ‘data’ -> [values]}

      - ‘tight’ : dict like {‘index’ -> [index], ‘columns’ -> [columns], ‘data’ -> [values], ‘index_names’ -> [index.names], ‘column_names’ -> [column.names]}

      - ‘records’ : list like [{column -> value}, … , {column -> value}]

      - ‘index’ : dict like {index -> {column -> value}}

      Added in version 1.4.0: ‘tight’ as an allowed value for the `orient` argument

    intoclass, default dict

      The collections.abc.MutableMapping subclass used for all Mappings in the return value. Can be the actual class or an empty instance of the mapping type you want. If you want a collections.defaultdict, you must pass it initialized.

    indexbool, default True

      Whether to include the index item (and index_names item if orient is ‘tight’) in the returned dictionary. Can only be `False` when orient is ‘split’ or ‘tight’.

      Added in version 2.0.0.

  Returns:
    dict, list or collections.abc.MutableMapping

      Return a collections.abc.MutableMapping object representing the DataFrame. The resulting transformation depends on the orient parameter.

  Examples

      >>> df = pd.DataFrame({'col1': [1, 2],
      ...                    'col2': [0.5, 0.75]},
      ...                   index=['row1', 'row2'])
      >>> df
            col1  col2
      row1     1  0.50
      row2     2  0.75
      >>> df.to_dict()
      {'col1': {'row1': 1, 'row2': 2}, 'col2': {'row1': 0.5, 'row2': 0.75}}

  You can specify the return orientation.

      >>> df.to_dict('series')
      {'col1': row1    1
               row2    2
      Name: col1, dtype: int64,
      'col2': row1    0.50
              row2    0.75
      Name: col2, dtype: float64}

      >>> df.to_dict('split')
      {'index': ['row1', 'row2'], 'columns': ['col1', 'col2'],
       'data': [[1, 0.5], [2, 0.75]]}

      >>> df.to_dict('records')
      [{'col1': 1, 'col2': 0.5}, {'col1': 2, 'col2': 0.75}]

      >>> df.to_dict('index')
      {'row1': {'col1': 1, 'col2': 0.5}, 'row2': {'col1': 2, 'col2': 0.75}}

      >>> df.to_dict('tight')
      {'index': ['row1', 'row2'], 'columns': ['col1', 'col2'],
       'data': [[1, 0.5], [2, 0.75]], 'index_names': [None], 'column_names': [None]}

  You can also specify the mapping type.

      >>> from collections import OrderedDict, defaultdict
      >>> df.to_dict(into=OrderedDict)
      OrderedDict([('col1', OrderedDict([('row1', 1), ('row2', 2)])),
                   ('col2', OrderedDict([('row1', 0.5), ('row2', 0.75)]))])

  If you want a defaultdict, you need to initialize it:

      >>> dd = defaultdict(list)
      >>> df.to_dict('records', into=dd)
      [defaultdict(<class 'list'>, {'col1': 1, 'col2': 0.5}),
       defaultdict(<class 'list'>, {'col1': 2, 'col2': 0.75})]
