On the topic, you might want to have a look at a talk I held at EuroPython 2016 on valuation of a code base (in the context of valuation of a Python company): https://downloads.egenix.com/python/EuroPython-2016-Python-Startup-Valuation.pdf (1596930 bytes) Video: https://www.youtube.com/watch?v=nIoE3KJxK6U There are a few things you can do with metrics to figure out how good a code base is. Of course, in the end you always have to do a code review, but the metrics are a good indicator of where to start looking for possible issues. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Sep 21 2017) >>> Python Projects, Coaching and Consulting ... http://www.egenix.com/ >>> Python Database Interfaces ... http://products.egenix.com/ >>> Plone/Zope Database Interfaces ... http://zope.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
