Answer 1

Code

def remove_pattern(input_txt, pattern):
    r = re.findall(pattern, input_txt)
    for i in r:
        input_txt = re.sub(i, '', input_txt)
    return input_txt    

combi['tidy_tweet'] = np.vectorize(remove_pattern)(combi['tweet'], "@[\w]*") 

Result:-

Thanks :)

Answer 2

import re
Tweet = "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.

Answer 3

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

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