') Let us consider an example where have an equation for three input variables, x, y and z. Our program will ask the user to enter the values for both lists and then it will create one dictionary by taking the values. In this example we created a function mergeDictionary (dis1,dis2). Dictionary in Python is an unordered collection of data values, used to store data values like a map, which unlike other Data Types that hold only single value as an element, Dictionary holds key:value pair. To create a Dictionary, use {} curly brackets to construct the dictionary and [] … It is very easy to take more than one input in one line in python, you can just use x= [int (x) for (x) in input ().split ()] where we are storing multiple values in the form of list.
