Adding Version Control / Numbering (?) to Python Project

With my Java projects at present, I have full version control by declaring it as a Maven project. However I now have a Python project that I'm about to tag 0.2.0 which has no version control. Therefore should I come accross this code at a later date, I won't no what version it is.

How do I add version control to a Python project, in the same way Maven does it for Java?

First, maven is a build tool and has nothing to do with version control. You don't need a build tool with Python -- there's nothing to "build".

Some folks like to create .egg files for distribution. It's as close to a "build" as you get with Python. This is a simple setup.py file.

You can use SVN keyword replacement in your source like this. Remember to enable keyword replacement for the modules that will have this.

__version__ = "$Revision$"

That will assure that the version or revision strings are forced into your source by SVN.

You should also include version keywords in your setup.py file.

Ants's answer is correct, but I would like to add that your modules can define a __version__ variable, according to PEP 8, which can be populated manually or via Subversion or CVS, e.g. if you have a module thingy, with a file thingy/__init__.py:

___version___ = '0.2.0'

You can then import this version in setup.py:

from distutils.core import setup
import thingy
setup(name='thingy',
      version=thingy.__version__,
      py_modules=['thingy'],
      )

Create a distutils setup.py file. This is the Python equivalent to maven pom.xml, it looks something like this:

from distutils.core import setup
setup(name='foo',
      version='1.0',
      py_modules=['foo'],
      )

If you want dependency management like maven, take a look at setuptools.
