如何从字符串中提取两个具有相同前言的单词？

def extract_words_with_common_prefix(string):
    words = string.split(" ")  # 使用空格作为分隔符拆分字符串为单词列表
    common_prefix_words = []
    
    for i in range(len(words)-1):
        if words[i].startswith(words[i+1][:len(words[i])]):  # 比较前缀是否相同
            common_prefix_words.extend([words[i], words[i+1]])  # 提取具有相同前缀的两个单词
            
    return common_prefix_words

# 示例用法
string = "apple appstore application apply book cookbook cook"
result = extract_words_with_common_prefix(string)
print(result)  # 输出：['appstore', 'application']
