Python sort list of dictionaries alphabetically how to#
Here is some code showing how to use the reverse parameter of the sort() method in Python: False tells Python to sort in ascending (lowest to highest) order, while True says to sort by descending (highest to lowest) order. The reverse parameter uses a boolean value of either True or False, with False being the default setting. If we wanted to change the order of the list so that it is sorted by highest to lowest, we can use the reverse parameter. The order of elements in power_level is now: The order of elements in power_level is:
If you run this code in your code editor or IDE, you get the following result: This causes the list to be sorted from lowest to highest value by default, which, in this instance, changes the order of our list. We then use the sort() method on our list, by appending. This code example creates a list called power_level and assigns it the values: 100, 90, 80, and 50. Print("The order of elements in power_level is now: ",power_level) Print("The order of elements in power_level is: ",power_level) # Sorting a list of numbers in Python with sort()
However, sort() does have two optional parameters you can use to change this default sorting behavior.īefore we delve into the optional sort() parameters, however, let’s take a look at some sample code showing how to sort Python lists using the sort() method: If you use sort() on a list of strings, that list will be sorted in alphabetical order by default. When using the sort() method on a list, the default sort method sorts a list containing numeric values in order of their values. Remember, lists are mutable – or changeable – and therefore there is no real need to create a brand new instance of a list when you can’t simply modify the order of the elements in the existing list. It is used to change the existing list by reordering its elements, versus actually creating a brand new list. The first is known as the sort() method, which is a method that belongs specifically to lists and, as such, can only be used on lists. In Python, there are two primary ways to sort a list. Print("The third element in our villains list is:",villains) Print("The second element in our villains list is:",villains) Print("The first element in our villains list is:",villains) To access a particular element, we do so in the following manner: However, when we use or reference elements in a list, always remember that the first element starts at position ‘0’ and not position ‘1’ as you would expect. The first element is ‘Thanos, the second element is ‘Doctor Doom’, and ‘Kingpin’ is the third element. Mixed_list = ĭuplicate_list = Īs stated, lists are made up of one or more elements. # Creating a list with multiple, mixed types of values # Creating a list with multiple number values # Creating a list with multiple string elements # Creating a list with one string element In Python, we create a list in the following manner: Python lists are mutable, meaning that the information inside of them can be changed. Each of these elements is placed between a pair of square brackets – or – and separated by commas. Python lists are ordered data structures that are made up of one or more elements that represent data or information.

If so, feel free to read or review these parts to our Python programming guide: Before we begin, however, you might want to refresh your memory regarding some of the basics of Python programming. We will also learn the sorted() function, which you can use to sort any type of iterable. In particular, we will be learning how to sort lists in Python using the sort() method, which is a list method used to sort lists specifically. While it is meant for beginning to intermediate developers, it can also be a handy reference for veteran programmers as well.
