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
distutils has a set of version classes with comparisons.
In [1]:from distutils import version
In [2]:version?
Type: module
Base Class: <type 'module'>
String Form: <module 'distutils.version' from '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/distutils/version.pyc'>
Namespace: Interactive
File: /System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/distutils/version.py
Docstring:
Provides classes to represent module version numbers (one class for
each style of version numbering). There are currently two such classes
implemented: StrictVersion and LooseVersion.
Every version number class implements the following interface:
* the 'parse' method takes a string and parses it to some internal
representation; if the string is an invalid version number,
'parse' raises a ValueError exception
* the class constructor takes an optional string argument which,
if supplied, is passed to 'parse'
* __str__ reconstructs the string that was passed to 'parse' (or
an equivalent string -- ie. one that will generate an equivalent
version number instance)
* __repr__ generates Python code to recreate the version number instance
* __cmp__ compares the current instance with either another instance
of the same class or a string (which will be parsed to an instance
of the same class, thus must follow the same rules)
