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. ))z-alpharp )z-betar� )r� rp )r� r� )r� r< )z-finalr� )z-prer< )z-releaser� )z.releaser� )z-stabler� )r� rg )rr rg )� r� )z.finalr� )rs r� zpre$Zpre0zdev$Zdev0z([abc]|rc)[\-\.](\d+)$z\1\2z[\-\.](dev)[\-\.]?r?(\d+)$z.\1\2z[.~]?([abc])\.?r� r; r Nz\b0+(\d+)(?!\d)z (\d+[abc])$z\g<1>0z\.?(dev-r|dev\.r)\.?(\d+)$z.dev\2z-(a|b|c)(\d+)$z[\.\-](dev|devel)$z.dev0z(?![\.\-])dev$z(final|stable)$r� z\.?(r|-|-r)\.?(\d+)$z.post\2z\.?(dev|git|bzr)\.?(\d+)$z\.?(pre|preview|-c)(\d+)$zc\g<2>zp(\d+)$z.post\1)r~ r rL �replace�rer� r� )r ZrsZorigr� r r r �_suggest_normalized_version� s> r� z([a-z]+|\d+|[\.-])r< zfinal-�@)ry Zpreviewr� r� rz r� rg c C sr dd� }g }|| �D ]T}|� d�r^|dk rD|rD|d dkrD|�� q*|r^|d dkr^|�� qD|�|� qt|�S )Nc S st g }t �| �� �D ]R}t�||�}|rd|d d� krBdkrRn n |�d�}nd| }|�|� q|�d� |S )N�0r �9� �*�*final)� _VERSION_PARTrv rL �_VERSION_REPLACErW �zfillrP )r r` r= r r r � get_partsC s z _legacy_key.<locals>.get_partsr� r� rh z*final-Z00000000)r� �poprP rQ )r r� r` r= r r r � _legacy_keyB s r� c @ s e Zd Zdd� Zedd� �ZdS )r c C s t |�S r )r� r r r r r ] s zLegacyVersion.parsec C s8 d}| j D ](}t|t�r |�d�r |dk r d} q4q |S )NFr� r� T)r rU r r� )r r` r� r r r r7 ` s �zLegacyVersion.is_prereleaseN�r r r r r8 r7 r r r r r \ s r c @ s4 e Zd ZeZeej�Zded< e� d�Z dd� Z dS )r r� rF z^(\d+(\.\d+)*)c C s` ||k r dS | j �t|��}|s2t�d||� dS |�� d }d|v rV|�dd�d }t||�S )NFzACannot compute compatible match for version %s and constraint %sTr rg r )� numeric_rer^ r� �loggerZwarningru �rsplitr� )r rY r[ rT rx r r r r r� s s � z LegacyMatcher._match_compatibleN) r r r r rI �dictr9 rV r� �compiler� r� r r r r r k s r zN^(\d+)\.(\d+)\.(\d+)(-[a-z0-9]+(\.[a-z0-9-]+)*)?(\+[a-z0-9]+(\.[a-z0-9-]+)*)?$c C s t �| �S r )� _SEMVER_REr^ )r r r r r� � s r� c C sn dd� }t | �}|s t| ��|�� }dd� |d d� D �\}}}||d d�||d d� }}|||f||fS ) Nc S s8 | d u r|f}n$| dd � � d�}tdd� |D ��}|S )Nr rg c S s" g | ]}|� � r|�d �n|�qS )r� )rw r� )re r= r r r r� � r? z5_semantic_key.<locals>.make_tuple.<locals>.<listcomp>)rv rQ )r Zabsentr` r r r r � make_tuple� s z!_semantic_key.<locals>.make_tuplec S s g | ] }t |��qS r rb r� r r r r� � r? z!_semantic_key.<locals>.<listcomp>r� �|� r� )r� r ru ) r r� rx ru �major�minorZpatchry Zbuildr r r � _semantic_key� s r� c @ s e Zd Zdd� Zedd� �ZdS )r c C s t |�S r )r� r r r r r � s zSemanticVersion.parsec C s | j d d dkS )Nr r r� )r r0 r r r r7 � s z SemanticVersion.is_prereleaseNr� r r r r r � s r c @ s e Zd ZeZdS )r N)r r r r rI r r r r r � s r c @ s6 e Zd Zd dd�Zdd� Zdd� Zdd � Zd d � ZdS ) � VersionSchemeNc C s || _ || _|| _d S r )rM �matcher� suggester)r rM r� r� r r r r � s zVersionScheme.__init__c C s0 z| j �|� d}W n ty* d}Y n0 |S �NTF)r� rI r �r r r` r r r �is_valid_version� s z VersionScheme.is_valid_versionc C s. z| � |� d}W n ty( d}Y n0 |S r� )r� r r� r r r �is_valid_matcher� s z VersionScheme.is_valid_matcherc C s$ |� d�r|dd� }| �d| �S )z: Used for processing some metadata fields �,Nrh zdummy_name (%s))rO r� r r r r �is_valid_constraint_list� s z&VersionScheme.is_valid_constraint_listc C s | j d u rd }n | � |�}|S r )r� r� r r r �suggest� s zVersionScheme.suggest)N)r r r r r� r� r� r� r r r r r� � s r� c C s |S r r r r r r r> � r? r> )� normalized�legacyZsemanticr� �defaultc C s | t vrtd| ��t | S )Nzunknown scheme name: %r)�_SCHEMESrJ )rK r r r r � s r )*r Zloggingr� �compatr �utilr �__all__Z getLoggerr r� rJ r �objectr r9 r� rt r} r~ r r� r r� r� r� r� r� �Ir� r� r� r r r� r� r� r r r� r� r r r r r �<module> s� 1d =$ W � � � .r� � '���
