Some of the most interesting projects I stumble on as part of the public sector digitalisation in EU are made in Ruby on Rails (Southern Europe, especially Spain/Portugal), PHP (all of EU) and Python (Eastern Europe).
Having recently switched most of our internal development from C# to Python and Powershell I get it. I can’t imagine not building small web apps in Python and I imagine PHP and RnR are exactly the same experience of getting things to simply work extremely fast.
