Yes, some of the string functionality should be a pretty good introduction! Just make sure to comment in this PR which functions you are taking to avoid duplicate with :)

Here's a really awesome PR to show you how to get started: https://github.com/Eventual-Inc/Daft/pull/1867

Thanks @jaychia ! I will take the single-argument string kernels to start:

• .str.capitalize()
• .str.upper()
• .str.lower()
• .str.lstrip()
• .str.rstrip()
• .str.reverse()

Exploded all the checkboxes into individual issues so they can be assigned and tracked better.
