version

Version objects are comparable with standard operators:

>>> from versions import Version
>>> v1 = Version(1)
>>> v2 = Version.parse('2')
>>> v1 == v2
False
>>> v1 != v2
True
>>> v1 > v2
False
>>> v1 < v2
True
>>> v1 >= v2
False
>>> v1 <= v2
True

Version

class versions.version.Version(major, minor=0, patch=0, prerelease=None, build_metadata=None)

A package version.

Parameters:

• major (int) – Version major number
• minor (int) – Version minor number
• patch (int) – Version patch number
• prerelease (str, int or None) – Version prerelease

This class constructor is usually not called directly. For version string parsing, see Version.parse.

Parses a version_string and returns a Version object:

>>> Version.parse('1.0.0') > Version.parse('0.1')

True

exception versions.version.InvalidVersion(version)

Raised when failing to parse a version.
