On copies and views: updating pandas' internals (a.k.a. “Getting rid of the SettingWithCopyWarning”)
Joris Van den Bossche
Pandas’ current behavior on whether indexing returns a view or copy is confusing, even for experienced users. But it doesn’t have to be this way. We can make this aspect of pandas easier to grasp by simplifying the copy/view rules, and at the same time make pandas more memory-efficient. And get rid of the SettingWithCopyWarning.
