I am a long-time Python developer of over a decade and often focus on static analysis and distribution problems. Python is a diverse and quickly growing community and I love to contribute to it even as I try to keep up. I currently help ActiveState deliver secure, pre-build python projects to enterprise customers and individual developers.
Python offers us the ability to customize how it starts up. In some cases arbitrary python code can get executed before the first line of your module is reached. This is necessary for some of its dynamic nature, like virtualenvs but can also be harnessed to make the interpreter experience truly personal.
