Implemented as a named tuple with all ordering methods. Comparisons between X.Y.N and X.Y always treats the more specific number as larger. :param major: the most significant number in a version :param minor: next greatest significant number after major :param patch: next greatest significant number after minor :param rev: the least significant number in a version :raises TypeError: If invalid arguments are given. :raises ValueError: If invalid arguments are given. Examples: >>> Version(2, 9) == Version.from_str("2.9") True >>> Version(2, 9, 1) > Version.from_str("2.9.1") False >>> Version(3, 10) > Version.from_str("3.9.9.9") True >>> Version(3, 7) >= Version.from_str("3.7") True ���)�major�minor�patch�rev�returnc s t t| ��| ||||�S )zPDefault of -1 allows us to tiebreak in favor of the most specific number)�superr �__new__)�clsr r r r �� __class__r r r / s zVersion.__new__)�versionr c C s | t tt|�d���� S )a% Create a Version object from a string. :param version: A period-delimited version string, max 4 segments. :raises TypeError: Raised if invalid arguments are given. :raises ValueError: Raised if invalid arguments are given. :return: A Version object. �.)�list�mapr �split)r r r r r �from_str6 s zVersion.from_strc C s d| � |�kS )N� )�_compare_version��self�otherr r r �__gt__C s zVersion.__gt__c C s0 | j |j ko.| j|jko.| j|jko.| j|jkS �N�r r r r r$ r r r �__eq__F s � � �zVersion.__eq__c c s6 | j | j| j| jfD ] }|dkr,t|�V q q2qdS )z)Iterate over the version (drop sentinels)r N)r r r r r )r% �nr r r �__iter__N s zVersion.__iter__c C s d� | �S )Nr )�join�r% r r r �__str__V s zVersion.__str__c C s t t| ��S r( )�hashr r. r r r �__hash__Y s zVersion.__hash__)r& r c C sP | |kr dS | j |j kr dS | j|jkr,dS | j|jkr<dS | j|jkrLdS dS )z�Compare this Version to another. :param other: A Version object. :return: -1 if self > other, 1 if self < other, else 0 r r" r r) r$ r r r r# \ s zVersion._compare_version)r r r r )r r r �__doc__r r � classmethodr r! r' r* r, r/ r1 r# � __classcell__r r r r r s �� r r) )r �boundary_versionr c C s |dkpt �| �t �|�kS )a Determine if a deprecation message should be logged. :param version: The version in which the thing was deprecated. :param boundary_version: The version at which deprecation level is logged. :return: True if the message should be logged, else False.

Deduplicated deprecations are logged. :param deprecated: Noun to be deprecated. Write this as the start of a sentence, with no period. Version and extra message will be appended. :param deprecated_version: The version in which the thing was deprecated :param extra_message: A remedy for the user's problem. A good message will be actionable and specific (i.e., don't use a generic "Use updated key." if the user used a deprecated key). End the string with a period. :param schedule: Manually set the deprecation schedule. Defaults to 5 years. Leave a comment explaining your reason for deviation if setting this value. :param skip_log: Return log text rather than logging it.
