Next, create a dictionary called stock, which should contain the stock value for each item on your menu. Just like a Python list, the dictionary also allows comprehension to create new objects from an iterable in a loop. Print out the created dictionary. 20 Dec 2017. Our program will ask the user to enter the values for both lists and then it will create one dictionary by taking the values. The first approach is to use a row oriented approach using pandas from_records. In this article, you’ll learn about nested dictionary in Python.
