The first time I ever saw Python was when I was a young kid, in elementary or middle school, installing random Linux distributions on my machine that I had the CD for. One of them had "Loading Python" or something similar during the bootloader.
For actually writing Python, I started that in 2007. I had done a lot of really amateur toy programming as a kid: C, Pascal, etc. Python was the first language I picked up and learned how to do things beyond a loop and a function.
I have the first piece of Python I attempted to write. Enjoy:
