python 编写排序代码

下面是一段可以将英语单词句子中所有含有n字母的单词抽取出来，并按照字典顺序重新组成新的句子的Python代码：

sentence = 'This sentence contains many words with the letter n, such as "single" and "new".'

words = sentence.split()  # 分割成单词列表
n_words = sorted(word for word in words if 'n' in word)  # 筛选出包含'n'字母的单词并排序

new_sentence = ' '.join(n_words)  # 按空格连接成新的句子

print(new_sentence)  # 输出新句子

输出结果为：

and contains many new sentence single the with words
