pandas (original) (raw)

All the way back to the v0.16 docs, Series.str.partition (https://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.str.partition.html) has the signature Series.str.partition(pat=' ', expand=True), but the docs only talk about sep instead of pat.

I think the kwarg should be renamed to sep, which makes more sense for partitioning something than pat, which sounds like it's about a regex pattern.

Same thing applies to rpartition.
