Thanks I will look into these. The data going in is a list like this:['broadcast', '"d8on"', 'broadcast', '"d11on"']
With the output beng something like this. lst_0 = ['broadcast', '"d8on"'] lst_0 = ['broadcast', '"d11on"'] I have managed to use a dictionary as advised in a post on StackOverflow; not quite completed it as I am overwriting my lists each time. From your experience is it better to pursue the dictionary route or the zip tuple option.
