Hi,
I'm a relative newbie to python, and this NG, but it's certainly growing
on me.
One thing I'm missing is the increment/decrement operator from C, ie
x++, and its ilk. Likewise x += y.
is there any way of doing this in Python?
TIA, Tony

That doesn't seem to work:

Anyway, I'm no longer in a hole; thanks for all the excellent help. I'll
certainly review the design of my current project, to see if it can be
improved.
