an enumerate question

hi say i want to enumerate lines of a file eg for n,l in enumerate(open("file")): # print next line ie is there a way to print out the next line from current line using the above?. Or do i have to do a readlines() first to get it into a list eg d = open("file").readlines() for n, l in enumer
