DOC: remove regex argument from .str.rsplit docs

[MarcoGorelli]

Is your feature request related to a problem?

.str.split has a regex argument, which was added in #44185

Should .str.rsplit also take it?

EDIT

re.Pattern has split, but not rsplit, so this isn't straightforward without some crazy workaround. Let's just separate out the split and rsplit docs such that the rsplit ones don't have the regex argument

Currently, the argument is documented, but can't be passed https://pandas.pydata.org/docs/reference/api/pandas.Series.str.rsplit.html?highlight=rsplit#pandas.Series.str.rsplit

+1 on the consistency here.

Hello, I'm interested in working on this issue, looking around I assume this entails:

• Implementing similar logic from .str.split to .str.rsplit
• Writing additional test code

And I also noticed that the documentation has already been applied, so there's no need to update it right?

@banditelol apologies, I'd suggested this issue to a co-worker who I think had started working on it, but they hadn't commented "take" - let's quickly check with them. @dykim29 are you still working on this?

Hi @banditelol @MarcoGorelli I did start working on this! Still very new to this so didn’t comment ‘take’, apologies!

Okaay, good luck with the issue!
I'll look around again then
