Python으로 중첩된 JSON 파일 읽기 예제

import json

    """
    Read a nested JSON file and access deep fields via keys
    :param file_path: JSON file path
    :param keys: List of fields to access

# Example Usage
# Assuming JSON: {"user": {"profile": {"name": "Alice"}}}
value = read_nested_json("data.json", ["user", "profile", "name"])
print(value)  # Output "Alice"
