...ok...

...but that bit ain't right.

----- re.findall() example -----
>>> import re
>>> instring = """
... Just some text, any text,
... the more text the better...
... It needn't be good text.
... """
>>> target = re.compile('text')
>>> print re.findall(target,instring)
['text', 'text', 'text', 'text']
----- end example -----

Maybe what you want is...

import string
out_file.write(string.join(re.findall(text,x),"\n"))

...or, if you prefer...

y = re.findall(text,x)
y = string.join(y,'\n')
out_file.write(y)

...not playing with the interpreter enough.  ;-)
