get_intersection

trashpanda.get_intersection(source: pandas.core.frame.DataFrame, targeted_indexes: Union[List, pandas.core.indexes.base.Index]) → pandas.core.frame.DataFrame

trashpanda.get_intersection(source: pandas.core.series.Series, targeted_indexes: Union[List, pandas.core.indexes.base.Index]) → pandas.core.series.Series

Intersects Series or DataFrame by requested indexes. A subsection from the source is made for the targeted_indexes, which must not necessaraly be whithin the source.

Parameters

• source (Union[DataFrame, Series]) – Values from which an intersection will be retrieved.

• targeted_indexes (Index) – The indexes which the returned Series should contain.

Returns

Union[DataFrame, Series]

Examples

Usage with pandas.Series

>>> from pandas import Series
>>> sample_series = Series(list(range(3)), index=list(iter("abc")), name="foo")
>>> get_intersection(sample_series, ["b", "c", "d"])
b    1
c    2
Name: foo, dtype: int64
>>> get_intersection(sample_series, ["x", "y", "z"])
Series([], Name: foo, dtype: int64)

Usage with pandas.DataFrame

>>> from pandas import DataFrame
>>> sample_series = DataFrame(
...     list(range(3)), index=list(iter("abc")), columns=["foo"]
... )
>>> get_intersection(sample_series, ["b", "c", "d"])
   foo
b    1
c    2
>>> get_intersection(sample_series, ["x", "y", "z"])
Empty DataFrame
Columns: [foo]
Index: []
