如何用嵌套的json数组反序列化json对象

{
  "name": "John",
  "age": 30,
  "hobbies": [
    {
      "name": "reading",
      "level": "advanced"
    },
    {
      "name": "gaming",
      "level": "intermediate"
    }
  ]
}

import json

json_str = '''
{
  "name": "John",
  "age": 30,
  "hobbies": [
    {
      "name": "reading",
      "level": "advanced"
    },
    {
      "name": "gaming",
      "level": "intermediate"
    }
  ]
}
'''

data = json.loads(json_str)
name = data["name"]
age = data["age"]
hobbies = data["hobbies"]

print("Name:", name)
print("Age:", age)
print("Hobbies:")
for hobby in hobbies:
    hobby_name = hobby["name"]
    hobby_level = hobby["level"]
    print("- Name:", hobby_name)
    print("  Level:", hobby_level)
