Learn how you can sort a dictionary in Python.By default, dictionaries preserve the insertion order since Python 3.7.So the items are printed in the same order as they were inserted:data = {"a": 4, "e": 1, "b": 99, "d": 0, "c": 3} print(data) # {'a': 4, 'e': 1,...
Original dictionary: {'a': 1, 'c': 3, 'b': 5, 'd': 4} Sorted dictionary: [('a', 1), ('c', 3), ('d', 4), ('b', 5)] In the above example, we have used theoperatormodule to sort the items in the dictionary by value. The output of the above function is of type...
