350-401 · Question #702
Refer to the exhibit. Which Python code parses the response and prints "18:32:21.474 UTC Sun Mar 10 2019"?
The correct answer is B. print(response[result']['body']['simple_time']}. To correctly extract a specific value from a nested JSON structure in Python, you must use a sequence of dictionary key accesses matching the data's hierarchy.

Why each option
To correctly extract a specific value from a nested JSON structure in Python, you must use a sequence of dictionary key accesses matching the data's hierarchy.
This option contains a typo ('resut' instead of 'result') and uses an incorrect indexing or access method ('[0||'simple_time']'), which is not valid Python syntax for dictionary access.
Given a JSON response where 'simple_time' is nested within 'body', which is itself nested within 'result', the correct Python code to access this value is `response['result']['body']['simple_time']`. This path correctly navigates through the dictionary keys to retrieve the desired string.
This option incorrectly assumes that 'body' is a top-level key directly under 'response', skipping the 'result' key in the JSON structure.
This option contains a typo ('jresult' instead of 'result'), which would cause a KeyError when attempting to access the dictionary.
