Addendum: Polars doesn't even have index so no multiindex either. I haven't gotten deep enough into polars to understand why and what it breaks, but it feels wrong to replace pandas with something without index.
- Tarq0n 4y agoIndexes don't really do anything useful that's not covered by.group_by() and .over(). There is no loss of functionality.
- kzrdude 4y agoRight, it's still possible. But less close to hand and never automatic. Series also become less useful when they are just a sequence instead of an almost mapping (with an index) or a sparse sequence (with subset of larger index)
