Python is the interesting one of the bunch. I was exposed to it about 1995, when a coworker selected it as an embedded scripting language for our product. I didn't pay much attention to it at the time, as it was outside of my immediate responsibilities. It was selected again as an embedded scripting language at my next employer around 2003. This time I paid attention, and came to love it. It's the language that lets me turn my thoughts into results the fastest.
Thanks for asking the question, I've never stopped to think about my programming history in this much detail.
Throughout this thread, I've noted a distinct lack of dogma about everyone's evolution as a programmer. While I imagine there was some of it during the popular phase of many of these languages, it's nice to see mostly pragmatism in everyone's career journey.
