polars.Series.str.len_bytes#

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

Return the length of each string as the number of bytes.

Returns:

Series: Series of data type UInt32.

See also

len_chars

Notes

When working with non-ASCII text, the length in bytes is not the same as the length in characters. You may want to use len_chars() instead. Note that len_bytes() is much more performant (_O(1)_) than len_chars() (_O(n)_).

Examples

>>> s = pl.Series(["Café", "345", "東京", None])
>>> s.str.len_bytes()
shape: (4,)
Series: '' [u32]
[
    5
    3
    6
    null
]
