Extracting a Specific Value from a Nested JSON Data Structure

To extract a particular value from a complex nested JSON data structure, it is essential to understand the structure of the data. JSON follows a hierarchical representation using keys and values.

In the provided example, the key to the desired value is "creationTime," which is nested within multiple levels. To access this value, follow the path through the nested structure:

my_json['value']['queryInfo']['creationTime']

In this path, 'my_json' is the initial JSON dictionary, 'value' is the nested dictionary under the 'value' key, 'queryInfo' is the nested dictionary under 'value', and 'creationTime' is the value associated with that key.

To write code for this specific case, you can use the following syntax:

query_info = my_json['value']['queryInfo']
creation_time = query_info['creationTime']

More generally, to extract a value from a nested JSON structure, you can follow these steps:

1. Identify the path to the desired value: Examine the hierarchical structure of the JSON to determine the keys and values that lead to the desired value.
2. Translate the path into code: Use square brackets ([]) to access dictionaries and dot notation (.) to access values. For example:

my_json['first_key']['nested_key']['desired_value']
