Consider sentence : W U T Sample A B C D



I'm trying to use re.groups after re.search to fetch A, B, C, D (letters in caps after 'Sample'). There could be variable number of letters



Few unsuccessful attempts :



A = re.search('Samples([A-Z])s*([A-Z])*', 'W U T Sample A B C D')
A.groups()
('A', 'B')

A = re.search('Samples([A-Z])(s*([A-Z]))*', 'W U T Sample A B C D')
A.groups()
('A', ' D', 'D')

A = re.search('Samples([A-Z])(?:s*([A-Z]))*', 'W U T Sample A B C D')
A.groups()
('A', 'D')


I'm expecting A.groups() to give ('A', 'B', 'C', 'D')



Taking another example, 'XSS 55 D W Sample R G Y BH'
should give the output ('R', 'G', 'Y', 'B', 'H')



Any help much appreciated.
