python json 转储

Python中的json模块是处理JSON（JavaScript Object Notation）数据的标准工具。JSON是一种轻量级的数据交换格式，常用于前后端数据传输和存储。通过使用json模块，我们可以将Python数据结构转换为JSON格式的字符串，并将JSON字符串转换为Python数据结构。

python
import json
data = {
    "name": "John",
    "age": 30,
    "hobbies": ["reading", "coding", "playing"],
    "address": {
        "street": "123 Main St",
        "city": "New York"
    }
}
json_data = json.dumps(data)
print(json_data)

{"name": "John", "age": 30, "hobbies": ["reading", "coding", "playing"], "address": {"street": "123 Main St", "city": "New York"}}

python
import json
json_data = '{"name": "John", "age": 30, "hobbies": ["reading", "coding", "playing"], "address": {"street": "123 Main St", "city": "New York"}}'
data = json.loads(json_data)
print(data)

{'name': 'John', 'age': 30, 'hobbies': ['reading', 'coding', 'playing'], 'address': {'street': '123 Main St', 'city': 'New York'}}

python
import json
data = {
    "name": "John",
    "age": 30,
    "hobbies": ["reading", "coding", "playing"],
    "address": {
        "street": "123 Main St",
        "city": "New York"
    }
}
json_data = json.dumps(data)
print(json_data)
json_str = '{"name": "John", "age": 30, "hobbies": ["reading", "coding", "playing"], "address": {"street": "123 Main St", "city": "New York"}}'
data = json.loads(json_str)
print(data)
