The version string is expected to follow the pattern: 'major.minor.micro[releaselevel][serial]'. Each component of the version is extracted and returned as a tuple in the format (major, minor, micro, releaselevel, serial). Args ---- version (str): The version string to parse. Returns ------- version_info_t: A tuple containing the parsed version components. Raises ------ ValueError: If the version string is invalid and does not match the expected pattern. z^(\d+)z (?:\.(\d+))?z!(?:\.*([a-zA-Z+-][\da-zA-Z+-]*))?z (?:\.(.*))?zInvalid version string: r#rr)rematch ValueErrorintgroup_unpack_version)r'patternr-majorminormicro releaselevelserialrrrversion_string_as_tuple7s r8r3 str | intr4r5r6r7cCstt|t|t|||S)N)rr/)r3r4r5r6r7rrrr1asr1tuple[int, str, str]cCsNt|D] \}}|sn qt|pd||fSt|d|||d|fS)Nr) enumerateisdigitr/)r5r6r7indexcharrrr _splitmicroks r?)r)r)rrrrrrrr)rrrrrrrr!)r'rrr)rrrrr) r3r9r4r9r5r9r6rr7rrr)rr)r5rr6rr7rrr:)__doc__ __future__rr,difflibrtypingrrkomburrr r&r8r1r?rrrrs(      +
