The coming glut of Python devs is going to be a problem. Its an excellent language, I've used it for work for years, but its almost too powerful. A minimally skilled programmer can write mostly-functional Python programs while still not having the slightest notion of what they're doing, meaning the pressure for a developer to understand and improve their craft is often minimal.

If I were responsible for hiring developers into a Python post, I would only consider candidates to could show (ideally substantial) work in some other, strongly-typed, lower-level language. It hardly even matters if they haven't seen Python, a decent developer can become a useful Python programmer in a few hours. Python experience does not teach or demonstrate a decent understanding of software structure.
