JSON round-trips in Python

Serializing to JSON text and parsing it back.

import json

profile = {
    "name": "ada",
    "langs": ["python", "rust"],
    "active": True,
    "streak": 7,
}

text = json.dumps(profile, indent=2, sort_keys=True)
restored = json.loads(text)

compact = json.dumps(profile, separators=(",", ":"))
langs = restored["langs"]
same = restored == profile

How it works

1. dumps renders a dict as text, with options.
2. loads parses text back into Python objects.
3. The restored value equals the original.
