💡 Why This Matters

🌍 Real World

Online shoppers use AI-powered tools to quickly compare prices and reviews from many stores, saving time and money.

💼 Career

Understanding how AI filters and compares data is useful for roles in e-commerce, marketing, data analysis, and product management.

1

Create a list of products with prices and ratings

Create a list called products where each item is a dictionary with keys 'name', 'price', and 'rating'. Include these exact products: {'name': 'Laptop', 'price': 900, 'rating': 4.5}, {'name': 'Smartphone', 'price': 700, 'rating': 4.7}, {'name': 'Headphones', 'price': 150, 'rating': 4.2}, {'name': 'Smartwatch', 'price': 200, 'rating': 4.0}.

AI for Everyone

# Create the products list with dictionaries for each product
# Your code here

Hint

Use a list with dictionaries. Each dictionary should have keys 'name', 'price', and 'rating' with the exact values given.

2

Set a price limit for affordable products

Create a variable called price_limit and set it to 500. This will help the AI filter products that cost less than or equal to this amount.

AI for Everyone

products = [
    {'name': 'Laptop', 'price': 900, 'rating': 4.5},
    {'name': 'Smartphone', 'price': 700, 'rating': 4.7},
    {'name': 'Headphones', 'price': 150, 'rating': 4.2},
    {'name': 'Smartwatch', 'price': 200, 'rating': 4.0}
]
# Set the price_limit variable to 500
# Your code here

Hint

Just create a variable named price_limit and assign it the number 500.

3

Filter products within the price limit and good ratings

Create a list called affordable_good_products that includes products from products where the price is less than or equal to price_limit and the rating is greater than or equal to 4.0. Use a list comprehension with variables product for each item.

AI for Everyone

products = [
    {'name': 'Laptop', 'price': 900, 'rating': 4.5},
    {'name': 'Smartphone', 'price': 700, 'rating': 4.7},
    {'name': 'Headphones', 'price': 150, 'rating': 4.2},
    {'name': 'Smartwatch', 'price': 200, 'rating': 4.0}
]
price_limit = 500
# Create affordable_good_products list using list comprehension
# Your code here

Hint

Use a list comprehension with product as the variable. Check both price and rating conditions inside the comprehension.

4

Summarize the best affordable products

Create a list called best_products that contains only the 'name' of each product in affordable_good_products. Use a list comprehension with variable product.

AI for Everyone

products = [
    {'name': 'Laptop', 'price': 900, 'rating': 4.5},
    {'name': 'Smartphone', 'price': 700, 'rating': 4.7},
    {'name': 'Headphones', 'price': 150, 'rating': 4.2},
    {'name': 'Smartwatch', 'price': 200, 'rating': 4.0}
]
price_limit = 500

affordable_good_products = [product for product in products if product['price'] = 4.0]
# Create best_products list with product names
# Your code here

Hint

Use a list comprehension to extract the 'name' from each product in affordable_good_products.

Practice

1. What is one main benefit of using AI for comparison shopping?

easy

A. It helps find the best deals faster.

B. It guarantees the cheapest product every time.

C. It replaces all human decision-making.

D. It only shows products from one store.

Solution

1. Step 1: Understand AI's role in shopping

   AI quickly compares many products and prices from different places.

2. Step 2: Identify the main benefit

   This speed helps shoppers find good deals faster, saving time.

3. Final Answer:

   It helps find the best deals faster. -> Option A

4. Quick Check:

   AI speeds up deal finding = It helps find the best deals faster. [OK]

Hint: AI speeds up comparing prices and deals [OK]

Common Mistakes:

• Thinking AI always finds the absolute cheapest product
• Believing AI removes all human choice
• Assuming AI limits options to one store

2. Which of the following is a correct way AI helps in comparison shopping?

easy

A. AI only compares products from one brand.

B. AI manually visits each store to check prices.

C. AI ignores product reviews and ratings.

D. AI uses algorithms to analyze product features and prices.

Solution

1. Step 1: Identify AI's method

   AI uses algorithms (step-by-step rules) to analyze data automatically.

2. Step 2: Match correct AI behavior

   Analyzing product features and prices is how AI compares options effectively.

3. Final Answer:

   AI uses algorithms to analyze product features and prices. -> Option D

4. Quick Check:

   AI uses algorithms for comparison = AI uses algorithms to analyze product features and prices. [OK]

Hint: AI uses algorithms, not manual checks [OK]

Common Mistakes:

• Thinking AI checks prices by visiting stores manually
• Believing AI ignores reviews
• Assuming AI limits to one brand only

3. If an AI tool compares 3 products with prices $50, $45, and $55, and rates them by price only, which product will it recommend?

medium

A. The product priced at $45

B. The product priced at $50

C. The product priced at $55

D. All products equally

Solution

1. Step 1: Identify the lowest price

   Among $50, $45, and $55, $45 is the lowest price.

2. Step 2: Understand AI recommendation by price

   AI recommending by price means it picks the cheapest product.

3. Final Answer:

   The product priced at $45 -> Option A

4. Quick Check:

   Lowest price = $45 = The product priced at $45 [OK]

Hint: AI picks lowest price when rating by price [OK]

Common Mistakes:

• Choosing the middle price thinking it's average
• Picking the highest price by mistake
• Assuming AI recommends all equally

4. An AI comparison tool shows wrong prices for products. What is the most likely cause?

medium

A. The products are not available anywhere.

B. The user did not refresh the page.

C. The AI algorithm is outdated or has incorrect data.

D. The AI always shows the highest prices intentionally.

Solution

1. Step 1: Identify cause of wrong prices

   Wrong prices usually come from outdated or incorrect data in AI's system.

2. Step 2: Evaluate other options

   Refreshing page or product availability does not cause consistent wrong prices; AI does not intentionally mislead.

3. Final Answer:

   The AI algorithm is outdated or has incorrect data. -> Option C

4. Quick Check:

   Wrong prices = outdated or wrong AI data = The AI algorithm is outdated or has incorrect data. [OK]

Hint: Wrong prices usually mean bad or old AI data [OK]

Common Mistakes:

• Blaming user refresh instead of data issues
• Thinking AI shows highest prices on purpose
• Assuming products are unavailable everywhere
