2.有一段英文，请编程实现去掉由于编写错误连续重复出现的单词，正常重复不需要删除。 例如：This is is an apple, and that is a banana. 改为：This is an apple, and that is a banana.python

你可以通过使用Python的列表推导式来实现这个功能。这里是一个简单的例子：

def remove_consecutive_duplicates(input_string):
    words = input_string.split()
    result = [' '.join(word[0] for word in consecutive_group) for consecutive_group in groupby(words)]
    return ' '.join(result)

input_text = "This is is an apple, and that is a banana."
processed_text = remove_consecutive_duplicates(input_text)
print(processed_text)  # 输出：This is an apple, and that is a banana.

groupby函数在这里用于检测单词是否连续重复，如果是，则作为一个组处理；如果不是，则单独作为一个组。
