Need Of Sorting A Dictionary

A dictionary has a O(1) search time complexity whereas a list has a O(n) search time complexity, which makes dictionary is a viable option wherever necessary.Search keys by value in a dictionary
The dictionary object has an items() method which returns a list of all the items with their values, i.e., in the form of key-pairs. So, we’ll call this function and then traverse the sequence to search our desired value.

If the target value matches with some of the items in the dict object, then we’ll add the key to a temp list.

A sorted dictionary yields better understanding and clarity in handling the operations.
Sorting helps in making efficient analysis while working with any data structure.

How To Sort A Dictionary?

Sorting by keys
Sorting by values
Custom sorting algorithms – string, number
Reversing the sorted order

Sorting By Keys

We can use the in-built sorted function which will take any iterable and return a sorted list. We can use the keys in order to get a sorted dictionary in the ascending order.
