PandasArray.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 v were inserted before the indices, the order of self would be preserved.
Assuming that a is sorted:
side returned index i satisfies left self[i-1] < v <= self[i]right self[i-1] <= v < self[i]Parameters: - value : array_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).
- sorter : 1-D array_like, optional
Optional array of integer indices that sort array a into ascending order. They are typically the result of argsort.
Returns: - indices : array of ints
Array of insertion points with the same shape as value.
