Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...
Thesort()function is another method for sorting lists of lists in Python. Unlike thesorted()function,sort()works directly on the list itself, modifying it in place. This method is particularly useful when the original list needs to be rearranged without creating a new sorted list. ...
Similarly, you can also use thelist.sort()function to order a list in reverse order. it also takes reverse as a parameter to specify whether the list should be sorted in ascending (False) or descending (True) order. The default isreverse=False. To sort in reverse usereverse=True. 3.1. ...

Sorting Based on Absolute Value To sort a list of integers based on their absolute values, you can use the built-inabs()function as thekeyparameter: numbers =[5,-3,1,-8,-7] sorted_numbers =sorted(numbers, key=abs) print(sorted_numbers) ...

Another option for selecting the pivot is to find the median value of the array and force the algorithm to use it as the pivot. This can be done in O(n) time. Although the process is little bit more involved, using the median value as the pivot for Quicksort guarantees you will have...
