numpy.searchsorted() in Python Last Updated : 10 Dec, 2018 Summarize Comments Improve Suggest changes Share Like Article Like Report numpy.searchsorted() function is used to find the indices into a sorted array arr such that, if elements are inserted before the indices, the order of arr would be still preserved. Here, binary search is used to find the required insertion indices. Syntax : numpy.searchsorted(arr, num, side='left', sorter=None) Parameters : arr : [array_like] Input array. If sorter is None, then it must be sorted in ascending order, otherwise sorter must be an array of indices that sort it. num : [array_like]The Values which we want to insert into arr. 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 a). num : [array_like, Optional] array of integer indices that sort array a into ascending order. They are typically the result of argsort. Return : [indices], Array of insertion points with the same shape as num.

It modifies the original list in place, meaning it does not return a new list, but instead changes the list it is called on.

It creates and returns a new sorted list and leaves the original iterable unchanged. Let's start with a basic example of sorting a list of numbers using the sorted() function.Pythona = 3 min read Like
