Wos! Several different thoughts: An object using yield to return only the relevant pages, one at a time. Pop to remove the items from the list. A dictionary to map between the strings and the integers.
The dictionary was particularly unexpected. Eventually, I plan to change the string ports to device names. On the other hand, it looks like the only reason I have port numbers is to use as an index in things like this. After examining your suggestion, I realised that another thing I am interested in could be generalised: I want the complement of the set of ports in pages, given a universal set in tempList. Ignoring the break condition for the moment, and my problem with int(port)/str(port), would you have offered a different solution if I had asked for the relative complement of a small set? a= ['a','b','c'] b= ['b'] c= a-b #set theoretic difference, a\b, a.~b, ['a','c'] Steve.
