Python json

Python has built-in support for working with JSON data. The `json` module in Python can be used to parse JSON strings into Python objects, and to serialize Python objects into JSON strings.

Here's an example of parsing a JSON string into a Python object:

import json

json_string = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_string)

print(data["name"])  # Output: John
print(data["age"])   # Output: 30
print(data["city"])  # Output: New York

And here's an example of serializing a Python object into a JSON string:

import json

data = {
    "name": "John",
    "age": 30,
    "city": "New York"
}

json_string = json.dumps(data)

print(json_string)  # Output: {"name": "John", "age": 30, "city": "New York"}

In addition to parsing and serializing JSON data, the `json` module also provides functions for pretty-printing JSON data and for decoding JSON data incrementally as it is received (useful for processing large JSON files).
