pandas 1.4.2

NotesParametersReturns
__getitem__(self: 'ExtensionArrayT', item: 'PositionalIndexer') -> 'ExtensionArrayT | Any'

Notes

For scalar item , return a scalar value suitable for the array's type. This should be an instance of self.dtype.type .

For slice key , return an instance of ExtensionArray , even if the slice is length 0 or 1.

For a boolean mask, return an instance of ExtensionArray , filtered to the values where item is True.

Parameters

item : int, slice, or ndarray
  • int: The position in 'self' to get.

  • slice: A slice object, where 'start', 'stop', and 'step' are integers or None

  • ndarray: A 1-d boolean NumPy ndarray the same length as 'self'

  • list[int]: A list of int

Returns

item : scalar or ExtensionArray

Select a subset of self.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
