Input: \'hgfd 0022222233333 4444 5556555 000         


        

Answer 1

You could use the below regex to match all the longest digit sequences (starting with length = 5),

(\d)\1{4,}

DEMO

>>> s = "hgfd 0022222233333 4444 5556555 0000000"
>>> [x.group() for x in re.finditer(r"(\d)\1{4,}", s)]
['222222', '33333', '0000000']

Update:

(\d)(?:\s*\1\s*\1\s*\1)(?:\s*\1)+
