Openstack is a rather large Python codebase that powers some rather large public and private clouds from Rackspace to HP and even CERN. I'll be discussing the various technologies and processes that allow us to do that in Python. It's also one of the more popular platforms for scientific computing and data analysis. There are huge code-bases designed in Python that work quite well and continue to grow in adoption and usefulness. I don't see why anyone would advise against writing a substantial system in Python.
