如何对文本文件中相互重叠的单词进行单独统计

def count_overlapping_words(file_path):
    word_count = {}
    
    with open(file_path, 'r') as file:
        text = file.read()
        
        # 文本预处理
        text = text.lower()
        text = text.replace('.', '').replace(',', '')  # 去除标点符号
        
        # 单词分割
        words = text.split()
        
        # 统计单词出现次数
        for word in words:
            if word in word_count:
                word_count[word] += 1
            else:
                word_count[word] = 1
    
    # 输出统计结果
    for word, count in word_count.items():
        print(f"{word}: {count}")
