![]() ![]() Instead, you can use the items() method of the dictionary to return a list of key-value pairs, and then apply enumerate() to the list of key/value pairs. We know that dictionaries are unordered, there is no index to enumerate over. Let's see an example to sort a list of employee dictionaries by two keys: name and salary using sort() function. Iterate over all key-value pairs of dictionary by index.

The sorted() function can accept three parameters: the iterable, the key, and reverse. However, if you want to sort a list or dictionary by multiple elements, let's say two keys then the easiest way is to use the key parameter and tuple the keys that we want to sort. Sorting a list or dictionary can be easily done using the sort() method and sorted() function in python. We have seen how to use methods of the dictionary class in our program to sort the values in the order of their increasing values.In this article, we will learn how to sort a list or dictionary using multiple keys in python. In this tutorial, we have seen how to sort a dictionary based on its values using three different approaches in Python. Look at the example to understand the input-output format.
