💡 Hint

Common Mistakes

Using the wrong parameter name like 'offset' or 'page'.

Not providing a default value causing errors if parameter is missing.

The 'limit' parameter controls how many items to return. Using request.args.get('limit', 10) gets it or defaults to 10, then converts to int.

max_price = request.args.get('[2]')

💡 Hint

Common Mistakes

Confusing 'min_price' with 'max_price'.

Using generic names like 'price' instead of 'max_price'.

To filter by category and maximum price, use the query parameters named 'category' and 'max_price'.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension filtering items where 'category' matches and 'price' is less than max_price.

Rest API

filtered_items = {item: data[item] for item in data if data[item]['[1]'] == [2] and data[item]['[3]'] < max_price}

Drag options to blanks, or click blank then click option'
