The key has the value of a lambda function which tells the computer to sort by age in ascending order.Ī lambda function is an anonymous function without a name. We can use the sorted() method to sort this data by the student's age. In this example, we have a collection of tuples that represents the band student's name, age and instrument. We can also use the sorted() method on tuples. Print(sorted(my_sentence.split(), key=len, reverse=True)) my_sentence = "Jessica found a dollar on the ground" This modified example will now sort the list from largest to smallest. We can also modify this example and include the key and reverse arguments. Print(sorted(my_sentence.split(), key=len)) Print("Original sentence: ", my_sentence) Then we use sorted() to sort the words by length from smallest to largest. In this example, we have a string broken up into individual words using the split() method. Print("Sorted in descending order: ", sorted_numbers)Īnother key difference between sorted() and sort() is that the sorted() method accepts any iterable whereas the sort() method only works with lists. reverse=True tells the computer to reverse the list from largest to smallest. In this example, we have a list of numbers sorted in descending order. The sorted() method also takes in the optional key and reverse arguments. Print("Sorted in ascending order: ", sorted_numbers) In this example, we have a list of numbers that will be sorted in ascending order. One key difference between sort() and sorted() is that sorted() will return a new list while sort() sorts the list in place. Examples of iterables would be lists, strings, and tuples. This method will return a new sorted list from an iterable.

Print("Sorted: ", names) How to use the sorted() method in Python
In this example, reverse=True will tell the computer to sort the list in reverse alphabetical order. Reverse has a boolean value of True or False. key=len will tell the computer to sort the list of names by length from smallest to largest. In this example, we can use the len() function as the value for the key argument. Key has the value of a function that will be called on each item in the list. The sort() method can take in two optional arguments called key and reverse. # this will return None because the list is already sorted If the list is already sorted then it will return None in the console. In this example, we have a list of numbers and we can use the sort() method to sort the list in ascending order. This method does not have a return value.
This method takes a list and sorts it in place.

In this article, I will provide code examples for the sorted() and sort() methods and explain the differences between the two. In Python, you can sort data by using the sorted() method or sort() method.
