Python 标识列表项是否在字符串中

我试图创建一个嵌套的循环序列，它查看一系列停止字和一系列字符串，并确定每个停止字是否在每个列表项中。理想情况下，我希望能够将每个字符串中出现的单词添加到一个新列中，并将它们全部从字符串中删除

有人有小费吗？我的循环顺序是否错误

def remove_stops(text, customStops):
    """
    Removes custom stopwords.

    Parameters
    ----------
    text : the variable storing strings from which
        stopwords should be removed. This can be a string
        or a pandas DataFrame.
    customStops : the list of stopwords which should be removed. 

    Returns
    -------
    Cleansed lists.

    """
    for item in text:
        print("Text:", item)
        for word in customStops:
            print("Custom Stops: ", word)
            if word in item:
                print("Word: ", word)
                #Add word to list of words in item
                #Remove word from item

以下是您可以做的：

def remove_stops(text, customStops):
    found = {k:[] for k in text} # Dict for all found stopwords in text
    for i,item in enumerate(text):
        for word in customStops:
            text[i] = text[i].replace(word,'') # Remove all stopwords from each string, if the stopword is not in, the replace will just leave it as it is
            if word in item:
                found[item].append(word)
    return text, found

text = ['Today is my lucky day!',
        'Tomorrow is rainy',
        'Please help!',
        'I want to fly']

customStops = ['help', 'fly']

clean, found = remove_stops(text, customStops)

print(clean)
print(found)

输出：

['Today is my lucky day!',
 'Tomorrow is rainy',
 'Please !',
 'I want to ']


{'Today is my lucky day!': [],
 'Tomorrow is rainy': [],
 'Please help!': ['help'],
 'I want to fly': ['fly']}

如果您提供一些测试输入以及对remove_stops（）函数的调用，我相信会有人（比如我；-）可以帮助您。“转到新专栏”是什么意思？@Ronald感谢您添加此请求，这是我在SO上的第一篇帖子：）我以后一定会这么做！非常感谢你，安！你找到你想要的了吗？我有一个澄清的问题-将两个列表转换为字典的原因是为了加快迭代，还是为了确保停止词与初始文本正确匹配？当我尝试运行此操作时，我得到错误“Unhable type:'list'”，因为它试图从列表值创建字典键。有办法解决这个问题吗？谢谢安！显然，我试图使用列表列表创建键，但这是不可能的，所以我将列表展平并转换为字符串。
