I recently saw this:

Compares two version strings and returns a cmp() function

containing version strings.
The logic used is as follows: the string

distutils has a set of version classes with comparisons.

How about a simple string comparison?

I can't assume there are the same number of '.'s or there are the same
number of digits per version.
I don't know how the tuple comparison works offhand. But that seems
like it would work if you split it.
The suggestion with the "re" module seems generic enough and looks like
it will work as is.

the following works for many common cases:
import re
def cmpver(a, b):
def fixup(i):
try:
return int(i)
except ValueError:

Not by default AFAIK. How about something like (untested):
def test_version(v1, v2):
v1, v2 = v1.split('.'), v2.

Convert your version numbers into tuples:
(0, 1, 0) < (0, 1, 2)
(1, 876, 'b') < (1,
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
