在python中的字符串列表中找到确切的单词列表？

def find_exact_words(word_list, string_list):
    exact_words = [word for word in word_list if any(word == s for s in string_list.split())]
    return exact_words

# 测试示例
word_list = ["hello", "world"]
string_list = "hello, how are you? world is beautiful."

exact_words = find_exact_words(word_list, string_list)
print(exact_words)
