lmocsi opened a new issue, #37955:
URL: https://github.com/apache/arrow/issues/37955
### Describe the enhancement requested
It would be nice to have instead of chained replace_all's:
```
df =
(df.with_columns(pl.col('field1').str.replace_all('aa','1').str.replace_all('bb','2'),
pl.col('field2').str.replace_all('aa','1').str.replace_all('bb','2')
)
```
using a dict, something like:
```
conv = {'aa': '1','bb': '2'}
df = (df.with_columns(pl.col('field1').str.replace_all(conv),
pl.col('field2').str.replace_all(conv)
)
```
### Component(s)
