pandas.api.extensions.ExtensionArray.searchsorted¶
- ExtensionArray.searchsorted(value, side='left', sorter=None)[source]¶
Find indices where elements should be inserted to maintain order.
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.
