3.4. Parsing a Version String

“Parsing” in this context means to identify the different parts in a string. Use the function parse():

>>> Version.parse("3.4.5-pre.2+build.4")
Version(major=3, minor=4, patch=5, prerelease='pre.2', build='build.4')

Set the parameter optional_minor_and_patch=True to allow optional minor and patch parts. Optional parts are set to zero. By default (False), the version string to parse has to follow the semver specification:

>>> Version.parse("1.2", optional_minor_and_patch=True)
Version(major=1, minor=2, patch=0, prerelease=None, build=None)
