Note that in Python 3, a regular expression compiled from a :class:`str` has the ``re.UNICODE`` flag set. If it is undesirable to store this flag in a BSON regular expression, unset it first:: >>> pattern = re.compile('.*') >>> regex = Regex.from_native(pattern) >>> regex.flags ^= re.UNICODE >>> db.collection.insert_one({'pattern': regex}) :param regex: A regular expression object from ``re.compile()``. .. warning:: Python regular expressions use a different syntax and different set of flags than MongoDB, which uses `PCRE`_. A regular expression retrieved from the server may not compile in Python, or may match a different set of strings in Python than when used in a MongoDB query. .. _PCRE: http://www.pcre.org/ z3regex must be a compiled regular expression, not %s) isinstancer TypeErrortyper"r$r)r&r(rrr from_native8s zRegex.from_nativerr$r!rUnion[str, int]NonecCs`t|ttfstdt|||_t|trt||_dSt|tr(||_dStdt|)aRBSON regular expression data.
