Question

I’m trying to find some code that, given a string, will allow me to iterate over each line using the for loop construct, but with the added requirement that separate for loop constructs will not reset the iteration back to the beginning.

At the moment I have

sList = [line for line in theString.split(os.linesep)]
for line in SList
  ... do stuff

But successive for loops will reset the iteration back to the beginning.

Does something in python exist for this, or will I have to write one from scratch?

Use another iterator:

aList = range(10)
anIterator = iter(aList)

for item in anIterator:
    print item
    if item > 4: break

for item in anIterator:
    print item
