polars.Series.str.explode#

Series.str.explode() → Series[source]#

Returns a column with a separate row for every string character.

Deprecated since version 0.20.31: Use .str.split("").explode() instead. Note that empty strings will result in null instead of being preserved. To get the exact same behavior, split first and then use when/then/otherwise to handle the empty list before exploding.

Returns:

Series: Series of data type String.

Examples

>>> s = pl.Series("a", ["foo", "bar"])
>>> s.str.explode()  
shape: (6,)
Series: 'a' [str]
[
        "f"
        "o"
        "o"
        "b"
        "a"
        "r"
]
