# pandas.DataFrame.drop

`DataFrame.``drop`(labels=None, axis=0, index=None, columns=None, level=None, inplace=False, errors='raise')

  Drop specified labels from rows or columns.

  Remove rows or columns by specifying label names and corresponding axis, or by specifying directly index or column names. When using a multi-index, labels on different levels can be removed by specifying the level.

  Parameters:

  labels : single label or list-like

  > Index or column labels to drop.

  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 list-like

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

  > New in version 0.21.0.

  columns : single label or list-like

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

  > New in version 0.21.0.

  level : int or level name, optional

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

  inplace : bool, default False

  > If True, do operation inplace and return None.

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

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

  Returns:

  DataFrame

  > DataFrame without the removed index or column labels.

  Raises:

  KeyError

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