>That was only a small example of a message...the message contains several elements.  If I have the PID segment then I have OBR segment...an OBX, etc.  So it would have to cycle through finding each element that is in the message till the end.  I actually meant a list and not a dictionary...terminology confusion in my head.

But if it's fixed patterns you can either do a replace() 
in a loop over your patterns:

for pat in ['PID','OBR',....]
    h7string = h7string.replace('\n'+pat, h7string)

Or even build a regex that does it all in one.
(But the regex could get complex quickly!)
