pandas.api.extensions.ExtensionArray.searchsorted¶

ExtensionArray.searchsorted(value, side='left', sorter=None)[source]¶

Find indices where elements should be inserted to maintain order.

New in version 0.24.0.

Find the indices into a sorted array self (a) such that, if the corresponding elements in value were inserted before the indices, the order of self would be preserved.

Assuming that self is sorted:

side	returned index i satisfies
left	`self[i-1] < value <= self[i]`
right	`self[i-1] <= value < self[i]`

Parameters

valuearray_like: Values to insert into self.
side{‘left’, ‘right’}, optional: If ‘left’, the index of the first suitable location found is given. If ‘right’, return the last such index. If there is no suitable index, return either 0 or N (where N is the length of self).
sorter1-D array_like, optional: Optional array of integer indices that sort array a into ascending order. They are typically the result of argsort.

Returns

array of ints: Array of insertion points with the same shape as value.
