Given this string:

>>> s = """|Type=Foo
... |Side=Left"""
>>> print s
|Type=Foo
|Side=Left

I can match with this:

>>> m = re.search(r'^\|Type=(.*)$\n^\|Side=(.*)$',s,re.MULTILINE)
>>> print m.group(0)
|Type=Foo
|Side=Left
>>> print m.group(1)
Foo
>>> print m.group(2)
Left

But when I try and sub it doesn't work:

>>> rn = re.sub(r'^\|Type=(.*)$^\|Side=(.*)$', r'|Side Type=\2 \1',s,re.MULTILINE)
>>> print rn
|Type=Foo
|Side=Left

What very stupid thing am I doing wrong?
