# pandas.DataFrame.select_dtypes

DataFrame.select_dtypes(include=None, exclude=None)

  Return a subset of the DataFrame’s columns based on the column dtypes.

  Parameters:
    include, excludescalar or list-like

      A selection of dtypes or strings to be included/excluded. At least one of these parameters must be supplied.

  Returns:
    DataFrame

      The subset of the frame including the dtypes in `include` and excluding the dtypes in `exclude`.

  Raises:
    ValueError

      - If both of `include` and `exclude` are empty

      - If `include` and `exclude` have overlapping elements

      - If any kind of string dtype is passed in.

  See also

  `DataFrame.dtypes`

    Return Series with the data type of each column.

  Notes

  - To select all numeric types, use `np.number` or `'number'`

  - To select strings you must use the `object` dtype, but note that this will return all object dtype columns. With `pd.options.future.infer_string` enabled, using `"str"` will work to select all string columns.

  - See the numpy dtype hierarchy

  - To select datetimes, use `np.datetime64`, `'datetime'` or `'datetime64'`

  - To select timedeltas, use `np.timedelta64`, `'timedelta'` or `'timedelta64'`

  - To select Pandas categorical dtypes, use `'category'`

  - To select Pandas datetimetz dtypes, use `'datetimetz'` or `'datetime64[ns, tz]'`

  Examples

      >>> df = pd.DataFrame({'a': [1, 2] * 3,
      ...                    'b': [True, False] * 3,
      ...                    'c': [1.0, 2.0] * 3})
      >>> df
              a      b  c
      0       1   True  1.0
      1       2  False  2.0
      2       1   True  1.0

      4       1   True  1.0
      5       2  False  2.0
