contains(cat, key, container)

This is a helper method for __contains__ and CategoricalIndex.__contains__ .

Returns True if key is in cat.categories and the location of key in categories is in container .

Notes

This method does not check for NaN values. Do that separately before calling this method.

Parameters

cat : :class:`Categorical`or :class:`categoricalIndex`

key : a hashable object

The key to check membership for.

container : Container (e.g. list-like or mapping)

The container to check for membership in.

Returns

is_in : bool

True if key is in self.categories and location of key in categories is in container , else False.

Helper for membership check for key in cat .

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
