如何使用Processing JSON object解析如下所示的嵌套JSON文件？

import json

# 读取JSON文件
with open('data.json') as file:
    data = json.load(file)

# 解析JSON对象
# 假设JSON文件的结构如下：
# {
#   "name": "John",
#   "age": 30,
#   "address": {
#     "street": "123 Main St",
#     "city": "New York"
#   },
#   "hobbies": ["reading", "traveling"]
# }

# 获取顶层属性值
name = data['name']
age = data['age']

# 获取嵌套的JSON对象
address = data['address']
street = address['street']
city = address['city']

# 获取数组值
hobbies = data['hobbies']

# 遍历数组值
for hobby in hobbies:
    print(hobby)

# 输出结果
print(name)
print(age)
print(street)
print(city)
