reverse (optional): If set to True, the iterable is sorted in descending order; otherwise, it’s sorted in ascending order (default). Sorting Sets in Ascending Order To sort a set of values in ascending order, use the sorted() function like this: original_set = {5, 3, 1, 4, 2} ...

In this method, the sorted() function is employed to sort the characters of the input string. The reduce() function combines the sorted characters back into a single string using a lambda function. reduce() takes a function (in this case, a lambda function that concatenates two strings) and...
To sort the objects in descending order, you need to use the "reverse" parameter and set it to "True": Python list reverse example a = [1, 2, 3, 4] a.sort(reverse=True) print(a) # [4, 3, 2, 1] 2. Key If you need your sorting implementation, the sort method accepts a "...
When it comes to sorting, there’s no shortage of solutions. In this section, we’ll cover three of my favorite ways to sort a list of strings in Python.Sort a List of Strings in Python by Brute ForceAs always, we can try to implement our own sorting method. For simplicity, we’ll...

You’ve seen the differences between sorted() and .sort(), but when do you use which? Let’s say there is a 5k race coming up: The First Annual Python 5k. The data from the race needs to be captured and sorted. The data that needs to be captured is the runner’s bib number ...

Here, the lambda function takes a tuple `x` and returns a tuple `(x[0], -x[1])` as the key. The negative sign is used to sort the scores in descending order. Problem 4: Sorting a List of Custom Objects When working with custom objects, you can use lambda functions to define cus...
