Counting bytes in text in polars
len_bytes
100DaysOfPolars
The number of characters in text is not always the same as the number of bytes, especially when the text contains emojis. Below is a dataframe showing YouTube comments.
Count characters and bytes
To count the number of characters and bytes in each comment, use len_chars and len_bytes respectively. The code below shows how:
(df
.with_columns(Chars=pl.col('YouTube_Comment').str.len_chars(),
Bytes=pl.col('YouTube_Comment').str.len_bytes())
)

| YouTube_Comment | Chars | Bytes |
|---|---|---|
| str | u32 | u32 |
| "๐ค I don't think this works IRLโฆ | 31 | 34 |
| "๐๐" | 2 | 8 |
| "๐ฅ" | 1 | 4 |
| "Wow!" | 4 | 4 |
Note
An emoji with one character can have many bytes.
