Sorting a list of tuples in increasing order by the last element in each tuple is a common task in programming. Tuples are ordered collections of elements, and sometimes you might want to sort a list of tuples based on a specific element within each tuple.

## Problem Statement

You are given a list of tuples, where each tuple contains a sequence of elements. Your task is to implement a function in Python that sorts this list of tuples in increasing order based on the last element of each tuple.

## Python Program to Sort a List of Tuples in Increasing Order by the Last Element in Each Tuple

def sort_tuples_by_last_element(lst): return sorted(lst, key=lambda x: x[-1]) # Example list of tuples tuple_list = [(1, 4), (3, 2), (8, 9), (5, 7)] sorted_list = sort_tuples_by_last_element(tuple_list) print(sorted_list)

## How it Works

**Defining the Function:**We start by defining the`sort_tuples_by_last_element(lst)`

function. This function takes a list of tuples`lst`

as an argument.**Using the**Inside the function, we use the`sorted()`

Function:`sorted()`

function to perform the sorting. The`sorted()`

function takes two important parameters:`iterable`

: This is the list of tuples we want to sort.`key`

: This is a function that takes an element from the`iterable`

and returns a value based on which the sorting is done.

**Lambda Function for Sorting:**In the`key`

parameter of the`sorted()`

function, we use a lambda function to specify that we want to sort based on the last element of each tuple. The lambda function`lambda x: x[-1]`

takes a tuple`x`

and returns its last element, which is used for sorting.**Result:**The`sorted()`

function returns a new list containing the sorted tuples. This list is assigned to the`sorted_list`

variable.**Returning the Result:**Finally, the`sort_tuples_by_last_element()`

function returns the`sorted_list`

.
