如何提取包含连词的名词和形容词对

import jieba.posseg as pseg

def extract_noun_adj_pairs(text):
    sentences = text.split("。")  # 假设以句号作为句子分隔符
    pairs = []
    
    for sentence in sentences:
        words = pseg.cut(sentence)
        prev_word = None
        for word, flag in words:
            if prev_word is not None and flag.startswith("n") and prev_word in ["和", "或", "但是"]:
                pairs.append((prev_word, word))
            prev_word = word
    
    return pairs

text = "云计算和人工智能是当今IT互联网领域的热门话题。云计算和大数据相辅相成，可以为企业提供灵活的计算和存储资源。"
pairs = extract_noun_adj_pairs(text)
for pair in pairs:
    print(pair[0] + " + " + pair[1])
