If one or more groups are present in the pattern, return a list of groups; this will be a list of tuples if the pattern has more than one group.

Empty matches are included in the result unless they touch the beginning of another match.

print(re.findall(r'\b', 'what   @@@do  @@you @think'))
# ['', '', '', '', '', '', '', '']
