The response.text attribute from the Python requests library contains the raw response body as a string. The exhibit shows this string is in JSON format. To work with this data as a structured object in Python, it must be deserialized or parsed. The requests library provides a built-in method, .json(), which parses the JSON string into a Python dictionary. After parsing, the values for latitude and longitude can be accessed using their corresponding keys, 'lat' and 'lng', with standard Python dictionary syntax: dictionary['key'].

A. response.text is a string. Attempting to access it with dictionary-style keys like ['lat'] will result in a TypeError because strings are not subscriptable with string keys.

C. The .json() method in this case returns a single dictionary, not a list (JSON array). Accessing it with numerical indices like [0] will cause a KeyError.

D. Accessing response.text with numerical indices like [0] would retrieve the first character of the raw string ({), not the value associated with a key.

1. Official Vendor Documentation (Cisco Meraki): The Meraki Dashboard API documentation for the "Get device" endpoint (GET /devices/{serial}) shows that the response body is a JSON object containing keys such as lat and lng. This confirms the data structure shown in the exhibit.

2. Official Vendor Documentation (Python requests library): The official documentation for the requests library explicitly describes the use of the .json() method for handling JSON responses. It states

"There’s also a built-in JSON decoder

in case you’re dealing with JSON data... r.json()".

3. University Courseware (University of Michigan): Course materials for "Python for Everybody" explain how to parse JSON data retrieved from a web service. The materials demonstrate that after fetching data

it must be loaded from a string (if not using a library helper like .json()) into a dictionary to be accessed by key.
