Question

python 3

Define a function that uses two lists similar to the following to create a dictionary: items = ['laptop', 'tablet', 'smartphone', 'reader', 'camera'] price = [749, 199, 399, 99, 1149] The dictionary should have the names of the items as keys and the prices as values. After creating the dictionary, ask the user to enter the name of an item, and display its price if the item is in the dictionary. If the item is not in the dictionary then display an appropriate message. Two sample runs of the program might look like this: Which item's price do you want to know? camera The price of camera is $749 Which item's price do you want to know? iPod Sorry! iPod is not in our catalog.
