polars.Series.str.n_chars#

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

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

Returns:
Series

Series of data type UInt32.

Notes

If you know that you are working with ASCII text, lengths will be equivalent, and faster (returns length in terms of the number of bytes).

Examples

>>> s = pl.Series(["Café", None, "345", "東京"])
>>> s.str.n_chars()
shape: (4,)
Series: '' [u32]
[
    4
    null
    3
