polars.Series.str.lengths#

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

Get length of the string values in the Series (as number of bytes).

Returns:

Series: Series of data type UInt32.

Notes

The returned lengths are equal to the number of bytes in the UTF8 string. If you need the length in terms of the number of characters, use n_chars instead.

Examples

>>> s = pl.Series(["Café", None, "345", "東京"])
>>> s.str.lengths()
shape: (4,)
Series: '' [u32]
