pyspark.pandas.Series.nsmallest

Series.nsmallest(n=5)

Return the smallest n elements.

Parameters

nint, default 5

Return this many ascending sorted values.

Returns

Series

The n smallest values in the Series, sorted in increasing order.

See also

Series.nlargest

Get the n largest elements.

Series.sort_values

Sort Series by values.

Series.head

Return the first n rows.

Notes

Faster than .sort_values().head(n) for small n relative to the size of the Series object. In pandas-on-Spark, thanks to Spark’s lazy execution and query optimizer, the two would have same performance.

Examples

>>> data = [1, 2, 3, 4, np.nan ,6, 7, 8]
>>> s = ps.Series(data)
>>> s
0    1.0
1    2.0
2    3.0
3    4.0
4    NaN
5    6.0
6    7.0
7    8.0
dtype: float64

The n largest elements where n=5 by default.

>>> s.nsmallest()
0    1.0
1    2.0

5    6.0
dtype: float64

>>> s.nsmallest(3)
