9/4/2020 · All programmers will have to write code to sort items or data at some point. Sorting can be critical to the user experience in your application, whether it’s ordering a user’s most recent activity by timestamp, or putting a list of email recipients in alphabetical order by last name. Python

Reverse. This operation inverts the order of the elements. We can apply the reversed() view to any iterable collection. Here, we apply reversed to the result of the sorted built-in method. Then: We iterate over the reversed view with a for-loop. Reversed returns an

By default sorted will sort the list of tuple by 1st element in tuple i.e. on 0th index. So list of tuples (key / value pairs) is sorted by keys. Now we can iterate over this sort list of tuple i.e. all sorted keys value pairs from dictionary i.e.

Python has its own implementation of sort() function and another is sorted() function where sort() will sort list whereas, sorted function will return new sorted list from an iterable. The list.sort() function can be used to sort list in ascending and descending order and takes argument reverse which is by default false and if passed true then sorts list in descending order.

In Python to reverse a list, we have generally three ways. But the best way to achieve Python Reverse list is by using the reverse() function. Note: Every list object in python has a method called reverse() that you can call a list object and it will reverse the list in place.

This was done because the Python sorted() method returns sorted iterable in the form of lists. As we can observe from the output above, both lists and tuples were sorted in our desired way. Sorting in descending order using Python sorted() Now let us take a
