I've just realised (I think) why you insist on nesting loops.
You are trying to get the lines in groups?
There are various ways to do this but the easiest here is
to use next():
with open(period.txt') as infile:
for line in infile:
process first line
line = next(infile) # get second line
process second line
line = next(infile) # get third line
etc...
That way you don't read the whole file at one go which your
nested loop "solution" does. The for loop will effectively
read every 5th line (if you have 4 next() calls inside it)
But you may have to use a try/except clause to catch
a StopIteration(?) exception if the file does not have
a multiple of 5 lines in it.
