The items in the iterable will be filtered according to the specifier. :param prereleases: Whether or not to allow prereleases in the returned iterator. If set to ``None`` (the default), it will be intelligently decide whether to allow prereleases or not (based on the :attr:`prereleases` attribute, and whether the only versions matching are prereleases). This method is smarter than just ``filter(SpecifierSet(...).contains, [...])`` because it implements the rule from :pep:`440` that a prerelease item SHOULD be accepted if no other versions match the given specifier. >>> list(SpecifierSet(">=1.2.3").filter(["1.2", "1.3", "1.5a1"])) ['1.3'] >>> list(SpecifierSet(">=1.2.3").filter(["1.2", "1.3", Version("1.4")])) ['1.3', <Version('1.4')>] >>> list(SpecifierSet(">=1.2.3").filter(["1.2", "1.5a1"])) [] >>> list(SpecifierSet(">=1.2.3").filter(["1.3", "1.5a1"], prereleases=True)) ['1.3', '1.5a1'] >>> list(SpecifierSet(">=1.2.3", prereleases=True).filter(["1.3", "1.5a1"])) ['1.3', '1.5a1'] An "empty" SpecifierSet will filter items based on the presence of prerelease versions in the set. >>> list(SpecifierSet("").filter(["1.3", "1.5a1"])) ['1.3'] >>> list(SpecifierSet("").filter(["1.5a1"])) ['1.5a1'] >>> list(SpecifierSet("", prereleases=True).filter(["1.3", "1.5a1"])) ['1.3', '1.5a1'] >>> list(SpecifierSet("").filter(["1.3", "1.5a1"], prereleases=True)) ['1.3', '1.5a1'] Nr� )r% r� r+ r1 r� r rL r� )r r* r% r> �filteredr� r( r� r r r r+ � s$ , � zSpecifierSet.filterr� )NNr ) r r r r r. r r1 rH r2 r% r3 rX r r/ r! r r� r0 r$ r� r r5 r� r� r� r) r r r+ r r r r r� � sR ��� � ���� �:����r� )#r r, ri r� �typingr r r r r r r r �utilsr r r r. r� r r1 r� r r� r �ABCMetar r5 r� r� rl rg rk rp r� r r r r �<module> s0 ( 7 .
