tweepy problem to to get a list of retweeters

[komarek]

so
i have a script that takes a timeline from user X and parse all his last tweets and print out a list of people that retweeted those tweets (for each one of them)

the code is something like this:

for tweet in api.user_timeline(screen_name = "XXXXX", count=20):
    print("TWEET:", tweet.text)
    for reTweet in api.retweets(tweet.id):
        print("USER:", reTweet.user.screen_name)

and it's working perfect
EXCEPT for the tweets that are actually not created by X but just Retweeted... in this case i have an empty list of retweeters.

do you know how to fix this?
