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?
c= a-b #set theoretic difference, a\b, a.~b, ['a','c']
