I'm not sure the number of those should be a consideration, as you probably only need one or two of each. The quality or fitness for a particular purpose does matter, and I'll confess to not being up-to-date enough about that kind of software to make a good case for any particular package. They certainly exist for Python, and I can recall using Satchmo and Django CMS some time ago. Those satisfied the MVP in an afternoon criterion for a developer already familiar with them.
