pandas.Series.explode — pandas 1.0.5 documentation (original) (raw)

Series. explode(self) → ’Series’[source]¶

Transform each element of a list-like to a row, replicating the index values.

New in version 0.25.0.

Returns

Series

Exploded lists to rows; index will be duplicated for these rows.

Notes

This routine will explode list-likes including lists, tuples, Series, and np.ndarray. The result dtype of the subset rows will be object. Scalars will be returned unchanged. Empty list-likes will result in a np.nan for that row.

Examples

s = pd.Series([[1, 2, 3], 'foo', [], [3, 4]]) s 0 [1, 2, 3] 1 foo 2 [] 3 [3, 4] dtype: object

s.explode() 0 1 0 2 0 3 1 foo 2 NaN 3 3 3 4 dtype: object
