Write a Python program to get the top three items in a shop.

Visual Presentation:

Sample Solution:

Python Code:

# Import the 'nlargest' function from the 'heapq' module and the 'itemgetter' function from the 'operator' module.
from heapq import nlargest
from operator import itemgetter

# Create a dictionary 'items' with keys representing items and values as their corresponding prices.
items = {'item1': 45.50, 'item2': 35, 'item3': 41.30, 'item4': 55, 'item5': 24}

# Use the 'nlargest' function to find the three items with the largest prices from the 'items' dictionary.
# The 'key' argument specifies that the second element (price) of each key-value pair should be used for comparison.
for name, value in nlargest(3, items.items(), key=itemgetter(1)):
    # Print the name and price of the three items with the largest prices.
    print(name, value) 
	

Sample Output:

item4 55                                                                                                      
item1 45.5                                                                                                    
item3 41.3
