You can use the below given which gives you both keys and values in the output. Create a List of Dictionaries in Python Python program to print number of bits to store an integer and also the number in Binary format. To print dictionary items: key:value pairs, keys, or values, you can use an iterator for the corresponding key:value pairs, keys, or values, using dict.items(), dict.keys(), or dict.values() respectively and call print() function. Using one for loop, we will iterate through each element of the dictionary* one by one* and then print them out. print() converts the dictionary into a single string literal and prints to the standard console output. For this tutorial, we are using python 3. Tuple is a collection which is ordered and unchangeable. The for loop approach is best if you want to display the contents of a dictionary to a console whereas the json module approach is more appropriate for developer use cases. A Python dictionary contains key value pairs. The code will look like as below : Here, we are iterating through each element of the dictionary using a for loop. In the above code, first, we have print the original dictionary and its type. There were a number of good reasons for that, as you’ll see shortly. As with lists we can print out the dictionary by printing the reference to it. Python program to find out the perimeter of a triangle. Each key-value pair in the dictionary maps the key to its associated value making it more optimized. In this tutorial, we will learn how to print the keys and values of a dictionary in python.
