Dictionary is one of the important data types available in Python. We will have a list of tuples (each tuple consists of two elements) or just a list of elements. Finally, we return the sorted dictionary. The enumerate() method adds counter to the iterable. Equivalent to a[len(a):] = [x]. For printing the keys and values, we can either iterate through the dictionary one by one and print all key-value pairs or we can print all keys or values at one go. When using the iterators, we need to keep track of the number of items in the iterator. Enumerate a dictionary. just switch position of these two :for i in range(3): and for key, value in output_dictionary.items(): – Zhubei Federer yesterday on a jupyter notebook, the code in the question is producing the desired output!
