Remove Usernames From Twitter Data Using Python

I have fetched some data from Twitter using python. now I want to pre process it. how can I remove usernames if the tweet has username between two words and there is no space among

Solution 1:

importreTweet="Hello@username"
Tweet = re.sub('@[^\s]+','',Tweet)

This code will remove the @username and Hello will not be removed.

Solution 2:

importreTweet="Hello@username"
Tweet = re.sub('@[\w]+','',Tweet)

Building on @NegiBabu's solution, Twitter only allows alphanumeric handles and so [\w] works as a better regex for this task. For e.g. with my proposed regex you wouldn't allow for @app#le to be matched.
