У меня есть два pd DataFrame, который имеет колонки

Index(['content', 'title_and_description', 'source', 'published_at',
       'cryptobert_embedding', 'cryptobert_content_sentiment',
       'cryptobert_content_score',
       'cryptobert_title_and_description_sentiment',
       'cryptobert_title_and_description_score', 'finbert_content_sentiment',
       'finbert_content_score', 'finbert_title_and_description_sentiment',
       'finbert_title_and_description_score', 'Llama-3-8B_content_sentiment',
       'Llama-3-8B_content_score',
       'Llama-3-8B_title_and_description_sentiment',
       'Llama-3-8B_title_and_description_score',
       'Llama-3.2-3B_content_sentiment', 'Llama-3.2-3B_content_score',
       'Llama-3.2-3B_title_and_description_sentiment',
       'Llama-3.2-3B_title_and_description_score',
       'Phi-3.5-mini_content_sentiment', 'Phi-3.5-mini_content_score',
       'Phi-3.5-mini_title_and_description_sentiment',
       'Phi-3.5-mini_title_and_description_score',
       'Mistral-7B-v0.3_content_sentiment', 'Mistral-7B-v0.3_content_score',
       'Mistral-7B-v0.3_title_and_description_sentiment',
       'Mistral-7B-v0.3_title_and_description_score',
       'Gemma-2-27b_content_sentiment', 'Gemma-2-27b_content_score',
       'Gemma-2-27b_title_and_description_sentiment',
       'Gemma-2-27b_title_and_description_score',
       'Mistral-8x7B-v0.1_content_sentiment',
       'Mistral-8x7B-v0.1_content_score',
       'Mistral-8x7B-v0.1_title_and_description_sentiment',
       'Mistral-8x7B-v0.1_title_and_description_score'],
      dtype='object')

Index(['date', 'sentiment', 'source', 'subject', 'text', 'title', 'url',
       'cryptobert_embedding', 'cryptobert_content_sentiment',
       'cryptobert_content_score',
       'cryptobert_title_and_description_sentiment',
       'cryptobert_title_and_description_score', 'finbert_content_sentiment',
       'finbert_content_score', 'finbert_title_and_description_sentiment',
       'finbert_title_and_description_score', 'Llama-3-8B_content_sentiment',
       'Llama-3-8B_content_score',
       'Llama-3-8B_title_and_description_sentiment',
       'Llama-3-8B_title_and_description_score',
       'Phi-3.5-mini_content_sentiment', 'Phi-3.5-mini_content_score',
       'Phi-3.5-mini_title_and_description_sentiment',

       'Mistral-7B-v0.3_title_and_description_score'],
      dtype='object')

Мне нужно в цикле объединить их в DataFrame с такими колонками

'published_at', 'source', 'embedding_cryptobert',
        
        'cryptobert_content_sentiment',
        'cryptobert_content_score',
        'cryptobert_title_and_description_sentiment',
        'cryptobert_title_and_description_score', 
        
        'finbert_content_sentiment',
        'finbert_content_score', 
        'finbert_title_and_description_sentiment',
        'finbert_title_and_description_score'
        
        'Llama-3-8B_content_sentiment',
        'Llama-3-8B_content_score',
        'Llama-3-8B_title_and_description_sentiment',
        'Llama-3-8B_title_and_description_score',
        
        'Phi-3.5-mini_content_sentiment', 
        'Phi-3.5-mini_content_score',
        'Phi-3.5-mini_title_and_description_sentiment',
        'Phi-3.5-mini_title_and_description_score',
        
        'Mistral-7B-v0.3_content_sentiment', 
        'Mistral-7B-v0.3_content_score',
        'Mistral-7B-v0.3_title_and_description_sentiment',
        'Mistral-7B-v0.3_title_and_description_score'
