I would now like to plot a vs e for all the obj objects in nlist.
how do I do that? I tried
plot(nlist[:].a,nlist[:].e,'ko')
You have a list of objects that have attributes named a and e; these
are not attributes of the list. Try
plot([x.a for x in nlist], [x.e for x in nlist], 'ko')

Another idiom which I use a lot
a,e = zip(*[(o.a, o.e) for o in nlist])
or if I have a lot of attributes I want dumped into arrays
a,b,c,d = map(numpy.asarray, zip(*[(o.a, o.b, o.c, o.d) for o in data]))
