Python print dictionary keys and values : In this tutorial, we will learn how to print the keys and values of a dictionary in python. Note that the restriction with keys in Python dictionary is only immutable data types can be used as keys, which means we cannot use a dictionary of list as a key. 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! Intro. enumerate() method takes two parameters: iterable - a sequence, an iterator, or objects that supports iteration; start (optional) - enumerate() starts counting from this number. The key will equal the current number we are on while iterating through num_list, and its corresponding value is equal to the count of that number in num_list. count() is a list method that returns the number of times the value we pass in occurs in our list. Python provides another composite data type called a dictionary, which is similar to a list in that it is a collection of objects.. Here’s what you’ll learn in this tutorial: You’ll cover the basic characteristics of Python dictionaries and learn how to access and manage dictionary data.

The values can be a list or list within a list, numbers, string, etc. list.extend (iterable) Extend the list by appending all the items from the iterable. We will have a list of tuples (each tuple consists of two elements) or just a list of elements. If start is omitted, 0 is taken as start. 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. In Python, a dictionary is listed in curly brackets, inside these curly brackets, the values are declared. In a dictionary, you have an 'index' of words, and for each of them a definition. list.insert (i, x) Insert an item at a given position. Equivalent to a[len(a):] = iterable. Before jumping into the tutorial, let’s see an example of converting a list into a dictionary. Enumerate a dictionary. It is separated by a colon(:), and the key/value pair is separated by comma(,). The enumerate() method adds counter to the iterable. When using the iterators, we need to keep track of the number of items in the iterator. Finally, we return the sorted dictionary.
