In this example, you create an instance of SortableDict. Then, you call the .sort_by_values() method to sort the dictionary by grades in reverse order. Next, you call the .sort_by_keys() method to sort the dictionary alphabetically by student names, which are the keys. The highlighted...
We can also sort the dictionary by keys using theitems()function along with thelambdafunction. Pass theitems()function and lambda function into thesorted()function, it will sort the dictionary by keys and finally, get the sorted dictionary by keys using thedict()function. # Sort the dictionar...
