What an idiot I am.. Yes, I know that.. And I actually *had* working code laying around, but rather than opening it and copy-and-pasting, I simply rewrote it. I obviously meant: newlist[i] = int(e[0]) > The most used idiom for that is: > > newlist = [int(e[0]) for e in mylist] > Or better lazily if you want to create a set, avoiding the list > creation: > > newlist = set(int(e[0]) for e in mylist) ...completely avoiding the design issue I raised altogether. Thanks! Exactly what I was hoping for! :-) -- Kind regards, Jan Danielsson -- http://mail.python.org/mailman/listinfo/python-list
