Worth of [] +=

[Steve Juranich]

First off, I've only been hacking Python for about 2 months now, so please
be patient.

I'm a little confused about this whole thing of += with a list object.
Didn't we already have that with the list.append() function?  Does the +=
operate differently (so that end users like me will notice)?  If it does
work differently, what will be the benefit of += that list.append() didn't
have?

TIA
