JSON Data

main.py

import json
data = '{"name": "Ada", "age": 36}'
parsed = json.loads(data)
print(parsed["name"])

main.py

import json
data = {"city": "Paris", "pop": 2000000}
print(json.dumps(data))

{"city": "Paris", "pop": 2000000}

main.py

import json
data = {"a": 1, "b": 2}
print(json.dumps(data, indent=2))

{
  "a": 1,
  "b": 2
}

import json
data = '{"users": [{"id": 1}, {"id": 2}]}'
