I am trying to go through tweets of a particular user and get all replies on that tweet. I found that the APIv1.1 of twitter does not directly support it.
Is there a hack or a workaround on getting the replies for a particular tweet. I am using python Streaming API.
Here's a work around to fetch replies of a tweet made by "username" using the rest  API using tweepy
1) Find the tweet_id of the tweet for which the replies are required to be fetched
2) Using the api's search method query the following (q="@username", since_id=tweet_id) and retrieve all tweets since tweet_id
3) the results matching the in_reply_to_status_id to tweet_id is the replies for the post.
