res = [] for ele in reversed(sorted(test_dict.keys ())): res.append (ele) print("The reversed order of dictionary keys : " + str(res)) Output : The original dictionary is : 1: 'Gfg', 2: 'best', 4: 'the', 5: 'is' The reversed order of dictionary keys : [5, 4, 2, 1] Time Complexity: O (N), where N is the length of the input string. First we create the dict. For the sake of this example I've made sure the keys and the values are not in alphabetical or numerical order. The for loop iterates over the keys, k and values, v in ages.items. Each key/value pair in a dict is called an item thus we use .items (). We print the key and value.
