print(pretty_json_str) 1. 运行以上代码,就能够将格式化的JSON字符串输出到控制台。 示例代码 下面是完整的示例代码: importjson# 定义一个字典data={"name":"Alice","age":20,"city":"New York"}# 将字典转换为JSON字符串json_str=json.dumps(data)# 将JSON字符串转换为Python对象python_obj=json.loads...
Writing JSON to a file To write JSON to a file in Python, we can use json.dump() method. Example 4: Writing JSON to a file import json person_dict = {"name": "Bob", "languages": ["English", "French"], "married": True, "age": 32 } with open('person.txt', 'w') as jso...
PrettyPrint means JSON data should be correctly indented and easy-to-read format. In this section, we will cover the following. Write Indented and Pretty-printed JSON data into a file Read and PrettyPrint JSON file using Python Pretty-print JSON from the command line Sort JSON keys alphabetica...

首先在使用 requests 模块发送 post 请求的时候,数据可以通过 data 参数传递、也可以通过 json 参数传输。 所以await request.read() 得到的就是最原始的字节流,除了它之外还有 await request.json(),它在内部依旧会获取字节流,只不过获取之后会自动 loads 成字典。
