如何从这个JSON文件中获取单词

import json

def extract_words_from_json(json_file_path):
    with open(json_file_path, 'r') as file:
        json_data = json.load(file)

    words = []

    # 遍历JSON数据，提取包含单词的字段或属性的值
    def extract_words(data):
        if isinstance(data, dict):
            for key, value in data.items():
                extract_words(value)
        elif isinstance(data, list):
            for item in data:
                extract_words(item)
        elif isinstance(data, str):
            # 提取单词并添加到列表中
            words.extend(data.split())

    extract_words(json_data)

    # 处理单词，如去除标点符号、转换为小写等
    words = [word.strip('.,?!') for word in words]
    words = [word.lower() for word in words]

    return words

# 示例用法
json_file_path = 'example.json'
words = extract_words_from_json(json_file_path)
print(words)
