Here's an example of a Python dictionary in parsable JSON format that includes internet speed, average temperature for December, and price index for the mentioned cities: ```python import json data = { "internet_speed": { "Paris": 50, "Barcelona": 70, "Lisbon": 40, "Palermo": 30, "Gozo": 20 }, "average_temperature_december": { "Paris": 5, "Barcelona": 10, "Lisbon": 15, "Palermo": 20, "Gozo": 25 }, "price_index": { "Paris": 100, "Barcelona": 90, "Lisbon": 80, "Palermo": 70, "Gozo": 60 } } # Convert the dictionary to JSON format json_data = json.dumps(data, indent=4) # Display the JSON data print(json_data) ``` This dictionary contains nested dictionaries for each parameter: `internet_speed`, `average_temperature_december`, and `price_index`. Each city is assigned a value for each parameter. The `json` module is used to convert the dictionary into a JSON-formatted string, which is then printed to the console.
