Python NamedTuple function example: Get item information

Python NamedTuple Data Type: Exercise-5 with Solution

Write a Python function that takes a namedtuple as input of the item's name and price. Returns the item's name and price.

Sample Solution:

Code:

from collections import namedtuple

# Define a NamedTuple named 'Item' with fields 'name' and 'price'
Item = namedtuple("Item", ["name", "price"])

def get_item_info(item):
    return item.name, item.price

# Create instances of the Item NamedTuple
items = [
    Item(name="Mobile", price=300.00),
    Item(name="Desktop", price=1500.00),
    Item(name="Laptop", price=1200.00)
]

# Print the information of each item
for item in items:
    item_name, item_price = get_item_info(item)
    print("Item Name:", item_name)
    print("Item Price:", item_price)
    print()

Output:

Item Name: Mobile
Item Price: 300.0

Item Name: Desktop
Item Price: 1500.0

Item Name: Laptop
Item Price: 1200.0

In the exercise above, we define a NamedTuple named "Item" with fields 'name' and 'price'. The "get_item_info()" function takes a NamedTuple representing an item's name and price as input and returns a tuple containing the item's name and price.

Next we create a list 'items' containing instances of the "Item" NamedTuple representing different items. Using the "get_item_info()" function, we iterate through the list and print the information of each item.
