pandas.Series.drop

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:

labels:single label or list-like

Index labels to drop.

axis:{0 or ‘index’}

Unused. Parameter needed for compatibility with DataFrame.

index:single label or list-like

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

columns:single label or list-like

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

level:int or level name, optional

For MultiIndex, level for 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:

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.

Series.reindex

Return only specified index labels of Series.

Series.dropna

Return series without null values.

Series.drop_duplicates

Return Series with duplicate values removed.

DataFrame.drop

Drop specified labels from rows or columns.

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
