>>> import regex
>>> compiled_pattern = regex.compile("/d+")
>>> compiled_pattern.flags
8224

It's a bitfield, i.e. each bit represents the presence of a flag.
>>> re.compile("/d+", re.IGNORECASE).flags
34
>>> re.RegexFlag(34)
re.IGNORECASE|re.UNICODE
>>> int(re.IGNORECASE) | int(re.UNICODE)
34
>>> {f: int(f) for f in re.RegexFlag}
{re.ASCII: 256, re.IGNORECASE: 2, re.LOCALE: 4, re.UNICODE: 32, re.MULTILINE: 8, re.DOTALL: 16, re.VERBOSE: 64, re.TEMPLATE: 1, re.DEBUG: 128}
