How to stream tweets from a specified user (only stream when the tweet is published by this user) using tweepy

I tried the following codes:

    class MyListener(StreamListener):
        def on_data(self, data):
            print(data)
            return True

    listener = MyListener()
    auth = OAuthHandler(config.API_KEY, config.API_SECRET)
    auth.set_access_token(config.ACCESS_TOKEN, config.ACCESS_TOKEN_SECRET)
    stream = Stream(auth, listener)
    stream.filter(follow=['<user_id>'])  # assume this user is a celebrity

What I got when running this code, is many spam-tweets or retweets by other users. (assume this <user id> is a celebrity, who has millions of followers. The followers are sharing the tweets all the time)

But I want to stream the original tweets published only by this specific <user id>. How can I implement this? Thanks in advance.

Solution

The official documentation says that using the follow parameter you get :

Tweets created by the user.
Tweets which are retweeted by the user.
Replies to any Tweet created by the user.
Retweets of any Tweet created by the user.
Manual replies, created without pressing a reply button (e.g. “@twitterapi I agree”).

So you just have to skip tweets not posted by the specified user :

def on_status(self, status):
    if status.user.id_str != '<user_id>':
        return
    print(status.text)
