如何在使用tweepy抓取推文时排除转发

import tweepy

consumer_key = 'your_consumer_key'
consumer_secret = 'your_consumer_secret'
access_token = 'your_access_token'
access_token_secret = 'your_access_token_secret'

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

api = tweepy.API(auth)

tweets = api.search(q='your_keyword', tweet_mode='extended')

for tweet in tweets:
    if not tweet.retweeted:
        # 进行相应的处理操作
        print(tweet.full_text)
