def parse_json(json_str):

Parses a JSON string into a Python dictionary.

Arguments

json_str - A string containing valid JSON data

Returns

A Python dictionary representing the parsed JSON data

Raises

ValueError - If the input string is not valid JSON or if the JSON is not an object at the top level

Examples

import fastpy_rs

# Parse a simple JSON object
data = fastpy_rs.json.parse_json('{"name": "John", "age": 30, "active": true}')
print(data['name'])  # Output: John
print(data['age'])   # Output: 30

# Parse JSON with nested structures
nested = fastpy_rs.json.parse_json('{"users": [{"id": 1, "name": "Alice"}, {"id": 2, "name": "Bob"}]}')
print(nested['users'][0]['name'])  # Output: Alice

def serialize_json(obj):

Serializes a Python object to a JSON string.

Arguments

obj - A Python object to serialize (dict, list, str, int, float, bool, None)

Returns

A JSON string representation of the input object

Raises

ValueError - If the object contains types that cannot be serialized to JSON

Examples

import fastpy_rs

# Serialize a simple dictionary
data = {"name": "John", "age": 30, "active": True}
json_str = fastpy_rs.json.serialize_json(data)
print(json_str)  # Output: {"name":"John","age":30,"active":true}

# Pretty-print the JSON
pretty_json = fastpy_rs.json.serialize_json(data, pretty=True)
print(pretty_json)
# Output:
# {
#   "name": "John",
#   "age": 30,
#   "active": true
# }

Serializes a Python object (dict, list, str, int, float, bool, None) to a JSON string.
