May be the first thing which I should do is to improve my English:) My main point was that in many cases (in my experience) it is a waste of memory to store entire list for star variable (*b) instead of some kind of iterator or deferred evaluation.
How do you defer evaluating the second and subsequent items if you > evaluate the final two? Given: > > def gen(): > yield 999 > for i in range(100): > yield random.random() > yield 999 > yield 999 > > then > > a, ?*b, c, d = gen() If I can not copy at Python level, I can 'tee' when 'star_pos' is reached. In my usual practice, the main use that I encounter when see an assignment to a star variable is as a storage which is used only if the other vars match some criterion. With kind regards, -gdg
