I have learnt Python as my second language (after being forced to learn Java in the University). And after that, for almost all my tasks, I use Python, either for prototyping or the real thing. I am also actively taking part in all things Pythonic in my area, including training, talks, seminars, write-ups. Most of my blog posts are about Python. Professionally, Django took up for most of my Pythonic projects, although I write scripts here and now for task automation, migration etc. I have also wrote a GPS Server using the excellent Twisted framework and currently using Pandas/Numpy/Matplotlib for some data analysis tasks at work.
