在Python中，如何根据列表删除字符串中的某些单词？

def remove_words_from_string(string, words):
    # 将字符串按空格分割成单词列表
    word_list = string.split()
    # 使用列表推导式过滤掉需要删除的单词
    filtered_list = [word for word in word_list if word not in words]
    # 将过滤后的单词列表重新组合成字符串
    new_string = ' '.join(filtered_list)
    return new_string

# 测试代码
string = "Hello world, this is a test string."
words_to_remove = ["world", "test"]
new_string = remove_words_from_string(string, words_to_remove)
print(new_string)
