LangChain - Output Parsers

You want to parse a nested JSON string with JsonOutputParser like:

{"user": {"name": "Eve", "roles": ["admin", "user"]}}

What will the parsed Python object look like?

A{'user': {'name': 'Eve', 'roles': ['admin', 'user']}}

B{"user": {"name": "Eve", "roles": ["admin", "user"]}}

CA flat dictionary with keys 'user.name' and 'user.roles'

DA list containing the user dictionary

Step-by-Step Solution

Solution:

Step 1: Understand nested JSON parsing
JsonOutputParser converts nested JSON objects into nested Python dictionaries and lists.
Step 2: Map JSON structure to Python
The nested JSON with 'user' key containing a dict with 'name' and 'roles' list becomes a nested Python dict with the same structure.
Final Answer:
{'user': {'name': 'Eve', 'roles': ['admin', 'user']}} -> Option A
Quick Check:
Nested JSON parses to nested dict/list [OK]

Quick Trick: Nested JSON becomes nested dicts and lists in Python [OK]
