or a string iterable ? How can I do that. I have lots of '\r\n'
characters in the string which I think can be easier if it were made
into a list and I can easily see if the required value (its a numeral)
is present in it or not after some position or after some characters'
position.

I a little confused by what you are trying to do, but:
Strings are iterable.
>>for c in "hello":
.... print "look, a letter", c
....
look, a letter h
look, a letter e
look, a letter l
look, a letter l
look, a letter o
And indexable:
>>"hello"[0]
'h'
And converting to a list is done like this:
>>list("hello")
['h', 'e', 'l', 'l', 'o']
They also have some pretty nifty methods:
>>"hello\r\nworld\r\nlets\r\nsplit\r\n".split("\r\ n")
['hello', 'world', 'lets', 'split', '']
>>"hello world".index('world')
6
>>"hello world".index('l')
2
>>"hello world".index('l', 2+1)
3
>>"hello world".index('l', 3+1)
9
>>"hello world".index('l', 9+1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: substring not found
Hopefully some of that helps.
