If you want a release, check out Spring's download site for Spring Python.
If you want the latest source code type:
git clone git://git.springsource.org/spring-python/spring-python.git
That will create a new spring-python folder. This includes both the source code and the demo applications (PetClinic and SpringWiki). The master branch is for the latest development release (1.3). If you want to look at another version, you can checkout a tracking branch:
git checkout -tb 1.2.x origin/1.2.x
This will create a local branch that tracks the remote origin/1.2.x branch.
You can browse the code at http://git.springsource.org/spring-python
