Python program to insert an element into sorted list Last Updated : 16 Dec, 2024 Comments Improve Suggest changes Like Article Like Report Inserting an element into a sorted list while maintaining the order is a common task in Python. It can be efficiently performed using built-in methods or custom logic. In this article, we will explore different approaches to achieve this.Using bisect.insort bisect module provides the insort function which inserts an element into a sorted list at the correct position, bisect.insort and performs a binary search to find the correct position which makes it more efficient than manual iteration. Python import bisect a = [1, 3, 4, 7, 10] # Insert 5 into the list bisect.insort(a, 5) print(a) Output[1, 3, 4, 5, 7, 10] Let's explore some methods to insert an element into sorted list.Table of ContentUsing LoopUsing List ComprehensionUsing Sorting After AppendingUsing LoopThis approach involves manually iterating through the list to find the appropriate position for the new element and then using the insert method. Python # Sorted list a = [2, 5, 8, 12] b = 10 # Find the correct position for i in range(len(a)): if b < a[i]: a.insert(i, b) break else: lst.append(b) print(a) Output[2, 5, 8, 10, 12] Using List ComprehensionList comprehension can be combined with slicing to create a new sorted list with the element inserted. This method separates the list into parts based on comparison and combines them with the new element. Python a = [3, 6, 9, 15] # Element to insert b = 8 # Insert element and create new list new_lst = [x for x in a if x < b] + [b] + [x for x in a if x >= b] print(new_lst) Output[3, 6, 8, 9, 15] Using Sorting After AppendingThe element is appended to the list and then the list is sorted to restore order. Sorting ensures the list remains ordered after insertion. It is used for simplicity when list size is small. Python a = [4, 7, 11, 14] # Append and sort a.append(9) a.sort() print(a) Output[4, 7, 9, 11, 14] Comment More infoAdvertise with us Next Article Python program to insert an element into sorted list S Smitha Dinesh Semwal Follow Improve Article Tags : Python Python Programs python-list Python list-programs Practice Tags : pythonpython-list Similar Reads Python Program For Insertion Sort In A Singly Linked List We have discussed Insertion Sort for arrays.

Below is a simple insertion sort algorithm for a linked list. 1) Create an empty sorted (or result) list. 2) Traverse the given list, do following for every node. ......a) Insert curr 5 min read Shift Last Element to First Position in list - Python The task of shifting the last element to the first position in a list in Python involves modifying the order of elements such that the last item of the list is moved to the beginning while the rest of the list remains intact. For example, given a list a = [1, 4, 5, 6, 7, 8, 9, 12], the goal is to sh 3 min read Python | Assign range of elements to List Assigning elements to list is a common problem and many varieties of it have been discussed in the previous articles. This particular article discusses the insertion of range of elements in the list. Let's discuss certain ways in which this problem can be solved.

This can be achieved by first converting each string to an integer and then sorting the 3 min read How to Convert a List into Ordered Set in Python? The task is to turn a list into an ordered set, meaning we want to remove any duplicate items but keep the order in which they first appear. In this article, we will look at different ways to do this in Python.Using OrderedDict.fromkeys()OrderedDict.fromkeys() method removes duplicates from a list a 2 min read Python Program For Moving Last Element To Front Of A Given Linked List Write a function that moves the last element to the front in a given Singly Linked List. For example, if the given Linked List is 1->2->3->4->5, then the function should change the list to 5->1->2->3->4. Algorithm: Traverse the list till the last node.
