JSON to Python
This lesson is part of Web Developer Tools · All levels
Summary
JSON to Python converters convert JSON data into equivalent Python literal, such as dict, list, string, and number. The values of true, false, and null of JSON are mapped to True, False, and None. To read JSON from a file or API, use json modules with the functions json.load or json.loads, rather than copying raw text. For more serious projects, the results can be refined into a dataclass or a Pydantic model to make the data type clear.
Key points
- JSON objects become Python dict and arrays become lists
- True, false, and null are mapped to True, False, and None
- Json.loads read the JSON string, json.load read the file
- JSON keys are always stringed and accessible with quotes
- Dataclass or Pydantic helps to structure and validate
