I have a list of strings and i want to remove the stop words inside each string. The thing is, the length of the stopwords is much longer than the strings and I don't want to repeat comparing each string with the stopwords list. Is there a way in python that these multiple strings at the same time?

```
lis = ['aka', 'this is a good day', 'a pretty dog']
stopwords = [] # pretty long list of words
for phrase in lis:
    phrase = phrase.split(' ') # get list of words
    for word in phrase:
        if stopwords.contain(word):
            phrase.replace(word, '')

```

This is my current method. But these means I have to go through all the phrases in the list. Is there a way that I can process these phrases with only one time compare?

Thanks.
