Parse Nested JSON in Python

MediumPython

Problem

Write a Python script to parse a nested JSON file.

Implement parse_nested_json(json_text) to parse a JSON string and return a dictionary containing every leaf value. Use dot-separated keys for nested objects and bracket notation for array indexes, such as user.address.city and items[0].sku. Empty objects and arrays are treated as leaf values. Preserve JSON value types.

Signature: def parse_nested_json(json_text):

Return the flattened dictionary.

Constraints

  • json_text is a valid JSON string.
  • The parsed JSON may contain nested objects, arrays, strings, numbers, booleans, and null.
  • Object keys do not contain dots or bracket-style index syntax.
  • Return every leaf value exactly once.
  • Empty objects and arrays are recorded as leaf values.
