Coming from a background that exposed me to far too many languages, I
find the latter two examples (i.e. use try/except) to be horrible
solutions. It's not a matter of light/heavy weight, it's a matter of
using exceptions for normal loop flow control is a really bad idea.

Hi list!
I'm relatively new to Python, and one thing I can't seem to get over is
the lack of in-expression assignments, as present in many other
languages. I'd really like to know how Python regulars solve the
problems posed by that.
For example, I recently wanted to do this:
