python输出合并同义词代码

以下是一个简单的 Python 合并同义词的代码示例：

synonyms = {
    'happy': ['joyful', 'pleased', 'content'],
    'sad': ['unhappy', 'miserable', 'depressed']
}

def merge_synonyms(sentence):
    words = sentence.split()
    new_sentence = []
    for word in words:
        for key in synonyms:
            if word in synonyms[key]:
                new_sentence.append(key)
                break
        else:
            new_sentence.append(word)
    return ' '.join(new_sentence)

sentence = 'I am so joyful and pleased today!'
merged = merge_synonyms(sentence)
print(merged)  # Output: "I am so happy and happy today!"

该代码将同义词词典 `synonyms` 中的键值对中的所有同义词合并到一起，并替换原句子中的同义词为合并后的主词. 例如上面的句子中，joyful 和 pleased 被替换为 happy。
