pandas.Series.drop — pandas 2.3.1 documentation

Series.drop(labels=None, *, axis=0, index=None, columns=None, level=None, inplace=False, errors='raise')[source]#

Return Series with specified index labels removed.

Remove elements of a Series based on specifying the index labels. When using a multi-index, labels on different levels can be removed by specifying the level.

Parameters:

labelssingle label or list-like

Index labels to drop.

axis{0 or ‘index’}

Unused. Parameter needed for compatibility with DataFrame.

indexsingle label or list-like

Redundant for application on Series, but ‘index’ can be used instead of ‘labels’.

columnssingle label or list-like

No change is made to the Series; use ‘index’ or ‘labels’ instead.

levelint or level name, optional

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

inplacebool, 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:

Series or None

Series with specified index labels removed or None if inplace=True.

Raises:

KeyError

If none of the labels are found in the index.

Examples

>>> s = pd.Series(data=np.arange(3), index=['A', 'B', 'C'])
>>> s
A  0
B  1
C  2
dtype: int64

Drop labels B en C

>>> s.drop(labels=['B', 'C'])
A  0
dtype: int64

Drop 2nd level label in MultiIndex Series

>>> 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]])
>>> s = pd.Series([45, 200, 1.2, 30, 250, 1.5, 320, 1, 0.3],
...               index=midx)
>>> s
llama   speed      45.0
        weight    200.0
        length      1.2
cow     speed      30.0
        weight    250.0
        length      1.5
falcon  speed     320.0
        weight      1.0
        length      0.3
dtype: float64

>>> s.drop(labels='weight', level=1)
llama   speed      45.0
        length      1.2
cow     speed      30.0
        length      1.5
falcon  speed     320.0
        length      0.3
dtype: float64
