Python parsing

I've been trying to grasp this for hours and it's embarassing, but I can't figure it out.

I'm dealing with raw files that are created as one huge line, but there are 3 character combos that show where each line should have began.

So I'm trying to read the file in and write one out that's properly formatted.  I've been thinking about how to do it in python and perl and I have no fucking clue.

Help, /prog/?

but there are 3 character combos that show where each line should have began
Can you re-phrase that?  There are 3 different characters, and anywhere one appears is the beginning of a new line?

Sorry, that was vague.  There are certain combinations of characters (e.g. OBX, OBR) that should begin a new line.

So, it should be like this:

OBX(text)
OBX(text)
OBR(text)

But is instead like this:

OBX(text)OBX(text)OBR(text)...

sed -re 's/(OBX|OBR)/\n/g'

Wat.

DON'T HELP HIM!

Well, from looking up the syntax of sed, I found out about str.replace() in python.

Thanks, anon.

rawtext.replace(')',')\n')
