# pandas.DataFrame.drop

DataFrame.drop(labels=None, *, axis=0, index=None, columns=None, level=None, inplace=<no_default>, errors='raise')

  Drop specified labels from rows or columns.

  Remove rows or columns by specifying label names and corresponding axis, or by directly specifying index or column names. When using a multi-index, labels on different levels can be removed by specifying the level. See the user guide for more information about the now unused levels.

  Parameters:
    labels single label or iterable of labels

      Index or column labels to drop. A tuple will be used as a single label and not treated as an iterable.

    axis{0 or ‘index’, 1 or ‘columns’}, default 0

      Whether to drop labels from the index (0 or ‘index’) or columns (1 or ‘columns’).

    index single label or iterable of labels

      Alternative to specifying axis (`labels, axis=0` is equivalent to `index=labels`).

    columns single label or iterable of labels

      Alternative to specifying axis (`labels, axis=1` is equivalent to `columns=labels`).

    level int or level name, optional

      For MultiIndex, level from which the labels will be removed.

    inplace bool, default False

      If False, return a copy. Otherwise, do operation in place and return None.

      Deprecated since version 3.1.0: This keyword is deprecated and will be removed in pandas 4.0. See PDEP-8 In-place methods in pandas for more details.

    errors{‘ignore’, ‘raise’}, default ‘raise’

      If ‘ignore’, suppress error and only existing labels are dropped.

  Returns:
    DataFrame or None

      Returns DataFrame or None DataFrame with the specified index or column labels removed or None if inplace=True.

  Raises:
    KeyError

      If any of the labels is not found in the selected axis.

  See also

  `DataFrame.loc`

    Label-location based indexer for selection by label.

  `DataFrame.dropna`

    Return DataFrame with labels on given axis omitted where (all or any) data are missing.

  `DataFrame.drop_duplicates`

    Return DataFrame with duplicate rows removed, optionally only considering certain columns.

  `Series.drop`

    Return Series with specified index labels removed.

  Examples

      >>> df = pd.DataFrame(np.arange(12).reshape(3, 4), columns=["A", "B", "C", "D"])
      >>> df
         A  B   C   D

      1  4  5   6   7
      2  8  9  10  11

  Drop columns

      >>> df.drop(["B", "C"], axis=1)
         A   D
      0  0   3
      1  4   7
      2  8  11

      >>> df.drop(columns=["B", "C"])
         A   D
      0  0   3
      1  4   7
      2  8  11

  Drop a row by index

      >>> df.drop([0, 1])
         A  B   C   D
      2  8  9  10  11

  Drop columns and/or rows of MultiIndex DataFrame

      >>> midx = pd.MultiIndex(
      ...     levels=[["llama", "cow", "falcon"], ["speed", "weight", "length"]],
      ...     codes=[[0, 0, 0, 1, 1, 1, 2, 2, 2], [0, 1, 2, 0, 1, 2, 0, 1, 2]],
      ... )
      >>> df = pd.DataFrame(
      ...     index=midx,
      ...     columns=["big", "small"],
      ...     data=[
      ...         [45, 30],
      ...         [200, 100],
      ...         [1.5, 1],
      ...         [30, 20],
      ...         [250, 150],
      ...         [1.5, 0.8],
      ...         [320, 250],
      ...         [1, 0.8],
      ...         [0.3, 0.2],
      ...     ],
      ... )
      >>> df
                      big     small
      llama   speed   45.0    30.0
              weight  200.0   100.0
              length  1.5     1.0
      cow     speed   30.0    20.0
              weight  250.0   150.0
              length  1.5     0.8

              length  0.3     0.2

  Drop a specific index combination from the MultiIndex DataFrame, i.e., drop the combination `'falcon'` and `'weight'`, which deletes only the corresponding row

      >>> df.drop(index=("falcon", "weight"))
                      big     small
      llama   speed   45.0    30.0

              weight  250.0   150.0
              length  1.5     0.8
      falcon  speed   320.0   250.0
              length  0.3     0.2

              weight  200.0
              length  1.5
      falcon  speed   320.0
              weight  1.0
              length  0.3

              weight  200.0   100.0
      cow     speed   30.0    20.0
