really? your pattern matches two digits, followed by a slash, followed
by a byte with the ASCII value 1, followed by a slash, followed by two
bytes with the ASCII value 1.
>>> '(\d{2})/\1/\1\1'
'(\\d{2})/\x01/\x01\x01'
in case you meant to write
r'(\d{2})/\1/\1\1'
(which is the same thing as '(\\d{2})/\\1/\\1\\1')
it's still not close; that pattern matches two digits, followed by a slash,
followed by the *same* two digits, followed by a slash, followed by the
same two digits, followed by the same two digits.
in other words, dates like 20/20/2020 and 12/12/1212.
try
'\d\d/\d\d/\d\d\d\d'
instead.
