I can code in 10 different languages, not including Python.  Python is by far the most backwards type of technology that I can think of.  Using it is completely counter-productive.  I can't take it serious.  I have plenty of tools in my toolbox.  I'll keep learning Python, and keep reading books, and keep using it...but strictly for fun.  I would never use this as a foundation for a mission critical business application.
