See Extension types for how to write your own extension that works with pandas. See ecosystem.extensions for a list of third-party libraries a dict of like-indexed Series objects. Getting, setting, and deleting columns works with the same syntax as the analogous dict operations: In [61]: df['one'] Out[61]: a 1.0 b 2.0 c 3.0 d NaN Name:

just the non-fill-value values (GH14167) • SparseArray.take now matches the API of pandas.api.extensions.ExtensionArray. take() (GH19506): – The default value of allow_fill has changed from False to ExtensionDtype. _metadata tuple to match the signature of your __init__ method. See pandas.api.extensions. ExtensionDtype for more (GH22476). New and changed methods • dropna() has been added (GH21185) ExtensionArray constructor, _from_sequence now take the keyword arg copy=False (GH21185) • pandas.api.extensions.ExtensionArray.shift() added as part of the basic ExtensionArray interface (GH22387). • searchsorted()
