Python regex to get all the words in a tweet that are not @mention or #hashtag

I want to get the words of a tweet that are not a mention (starting with @) or a hashtag (starting with #).

my code is like:

import re
pattern=r'(?u)\b\w\w+\b'
pattern=re.compile(pattern)
pattern.findall('this is a tweet #hashtag @mention')

The result with this regex is this is a tweet hashtag mention

but I don't want the hashtag and mention in the result. I want the result to be:

this is a tweet

Note that I can't use whitespace instead of \b because the output for .this is a tweet (note the . at the beginning) should also be [this, is, a, tweet] \b forces the start of a word to be any non-alphanumeric but if I use \s then this won't be in the results.

If you are open to solutions other than regex, then you can make use of filter and lambda function for desired result.

a = 'this is a tweet #hashtag @mention'
" ".join(filter(lambda x:x[0]!='#' and x[0]!='@' , a.split()))

'this is a tweet'

(?<![#@])\b\w+\b

You can use this.See demo.
