If you have a version string that isn't rational (i.e. NormalizedVersion doesn't like it) then you might be able to get an equivalent (or close) rational version from this function. This does a number of simple normalizations to the given string, based on observation of versions currently in use on PyPI. Given a dump of those version during PyCon 2009, 4287 of them: - 2312 (53.93%) match NormalizedVersion without change with the automatic suggestion - 3474 (81.04%) match when using this suggestion method @param s {str} An irrational version string. @returns A rational version string, or None, if couldn't determine one. s -alphaRY s -betaRi R� R� Rj R- s -finalR0 s -pres -releases .releases -stableR} RX R[ t s .finalR\ s pre$t pre0s dev$t dev0s ([abc]|rc)[\-\.](\d+)$s \1\2s [\-\.](dev)[\-\.]?r?(\d+)$s .\1\2s [.~]?([abc])\.?s \1R, i s \b0+(\d+)(?!\d)s (\d+[abc])$s \g<1>0s \.?(dev-r|dev\.r)\.?(\d+)$s .dev\2s -(a|b|c)(\d+)$s [\.\-](dev|devel)$s .dev0s (?![\.\-])dev$s (final|stable)$s \.?(r|-|-r)\.?(\d+)$s .post\2s \.?(dev|git|bzr)\.?(\d+)$s \.?(pre|preview|-c)(\d+)$s c\g<2>s p(\d+)$s .post\1( s -alphaRY ( s -betaRi ( R� RY ( R� Ri ( Rj R- ( s -finalR0 ( s -preR- ( s -releaseR0 ( s .releaseR0 ( s -stableR0 ( R} RX ( R[ RX ( R� R0 ( s .finalR0 ( R\ R0 N( Rg R R; t replaceRT R� Rp R5 ( R t rst origR� ( ( s? /usr/lib/python2.7/site-packages/pip/_vendor/distlib/version.pyt _suggest_normalized_version� sH s ([a-z]+|\d+|[\.-])R- Ra t previews final-R� Rj t @Rc c C s� d � } g } x� | | � D]� } | j d � r� | d k rg x' | rc | d d k rc | j � q@ Wn x' | r� | d d k r� | j � qj Wn | j | � q Wt | � S( Nc S s� g } x� t j | j � � D]j } t j | | � } | r d | d k oU d k n rl | j d � } n d | } | j | � q q W| j d � | S( Nt 0i t 9i t *s *final( t _VERSION_PARTR= R; t _VERSION_REPLACERK t zfillRC ( R RR R.
