推荐答案

python 字符串有一个内置的 split 方法，可以将字符串拆分为由空格字符分隔的单词列表 (doc)，它具有用于控制拆分单词方式的参数，然后您可以在列表中搜索你想要的词并返回下一个索引

python strings have a built in method split that splits the string into a list of words delimited by white space characters (doc), it has parameters for controlling the way it splits the word, you can then search the list for the word you want and return the next index

your_string = "This is a string"
list_of_words = your_string.split()
next_word = list_of_words[list_of_words.index(your_search_word) + 1]
