"Professional" just means they get paid for doing it. Professionals gave us the 2008 banking collapse, the Challenger shuttle explosion, the sinking of the Titanic, trench warfare in World War I, the Chernobyl nuclear meltdown, leaded petrol, "Battlefield Earth" the movie, and the BP Gulf of Mexico oil spill. Amateurs gave us the discovery of electricity, the Roomba, the original Apple computer, GNU software, Linux, Ogg/Vorbis, and the discovery of continental drift. While your modesty is a welcome change from n00bs who imagine that anything about Python that they misunderstood is a bug, don't sell yourself short. You don't need to be a computer scientist to identify bugs in software. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
