For–else execution behavior in Python - Mini Project: Build & Apply

For-else Execution Behavior

📖 Scenario: Imagine you are searching for a specific item in a list of products in a store. You want to know if the item is available or not.

🎯 Goal: You will write a Python program that uses a for loop with an else clause to check if a product is in the list. If the product is found, the program will print a message. If not, it will print a different message.

📋 What You'll Learn

Create a list of products with exact names

Create a variable for the product to search

Use a for loop with else to find the product

Print the correct message depending on whether the product is found

💡 Why This Matters

🌍 Real World

Searching for items in lists is common in shopping apps, inventory systems, and data filtering.

💼 Career

Understanding for-else helps write clear and efficient search code, useful in software development and data analysis.

1

Create the product list

Create a list called products with these exact items: 'apple', 'banana', 'orange', 'grape', 'mango'.

Python

# Create the list called products with the exact items
# Your code here

Need a hint?

Use square brackets [] to create a list and separate items with commas.

2

Set the product to search

Create a variable called search_item and set it to the string 'orange'.

Python

products = ['apple', 'banana', 'orange', 'grape', 'mango']
# Create the variable search_item and set it to 'orange'
# Your code here

Need a hint?

Use an equals sign = to assign the string 'orange' to search_item.

3

Use for-else to search the product

Write a for loop using item to iterate over products. Inside the loop, use an if statement to check if item == search_item. If yes, print Found orange! and use break. After the loop, add an else clause that prints orange not found..

Python

products = ['apple', 'banana', 'orange', 'grape', 'mango']
search_item = 'orange'
# Write a for loop with else to find search_item
# Your code here

Need a hint?

The else after a for runs only if the loop did not break.

4

Print the final output

Run the program and print the output. The output should be exactly Found orange!.

Python

products = ['apple', 'banana', 'orange', 'grape', 'mango']
search_item = 'orange'
for item in products:
    if item == search_item:
        print('Found orange!')
        break
else:
    print('orange not found.')
# Run the program to see the output

Need a hint?

Make sure you run the whole program to see the printed message.
