从python中的消息列表中查找最常用的单词对

from collections import Counter

    # 分词并统计单词出现次数
    word_counts = Counter()
    for message in messages:
        words = message.split()

    # 根据单词出现次数进行排序
    sorted_word_counts = sorted(word_counts.items(), key=lambda x: x[1], reverse=True)
    
    # 找出出现次数最多的单词对
    most_common_word_pair = sorted_word_counts[0]
    
    return most_common_word_pair

# 示例消息列表
