如何从整齐的数据创建json字符串

import json

# 创建数据对象
data = {
    "name": "John Doe",
    "age": 30,
    "is_student": False,
    "hobbies": ["reading", "coding", "traveling"],
    "address": {
        "street": "123 Main St",
        "city": "New York",
        "country": "USA"
    }
}

# 将数据转换为JSON格式
json_str = json.dumps(data)

# 打印生成的JSON字符串
print(json_str)

{"name": "John Doe", "age": 30, "is_student": false, "hobbies": ["reading", "coding", "traveling"], "address": {"street": "123 Main St", "city": "New York", "country": "USA"}}
