Is there a function for comparing version numbers?
E.g.
0.1.0 < 0.1.2 1.876b < 1.876c 3.2.2 < 3.4
FWIW,
>>> from distutils import version
>>> version_list = "3.4 3.2.2 1.867c 1.867b 0.1.2 0.1.0".split()
>>> version_list = map(version.LooseVersion, version_list)
>>> version_list.sort()
>>> print version_list
[LooseVersion ('0.1.0'), LooseVersion ('0.1.2'), LooseVersion ('1.867b'), LooseVersion ('1.867c'), LooseVersion ('3.2.2'), LooseVersion ('3.4')]
>>> print ' < '.join(map(str, version_list))
0.1.0 < 0.1.2 < 1.867b < 1.867c < 3.2.2 < 3.4

It should be noted that distutils.version provides a StrictVersion class that offers less flexible but more predictable ordering -- see the module docstrings for more details.
