Python - Structured Data Files

You receive a JSON string with nested data:

json_str = '{"user": {"name": "Sam", "age": 40}, "active": true}'

Which Python code correctly extracts the user's name after parsing?

Aimport json data = json.loads(json_str) print(data["name"])

Bimport json data = json.loads(json_str) print(data["user"]["name"])

Cimport json data = json.dumps(json_str) print(data["user"]["name"])

Dimport json data = json.load(json_str) print(data["user"]["name"])

Step-by-Step Solution

Solution:

Step 1: Parse JSON string to Python dictionary
json.loads converts the JSON string to a nested Python dict.
Step 2: Access nested dictionary keys
To get the user's name, access data["user"]["name"].
Final Answer:
import json data = json.loads(json_str) print(data["user"]["name"]) -> Option B
Quick Check:
Nested JSON access = data["user"]["name"] [OK]

Quick Trick: Use nested keys to access nested JSON data [OK]
