Python string -- swap positions in and out of parentheses

I have the following string:

"Person One (Something inside here) Second Thing (another thing) OK (something else)"

I need to get the following:

"Something inside here (Person One) another thing (Second Thing) something else (OK)"

Currently I am doing it like:

inside_parens = []
for item in str.split("("):
    if not ")" in item:
        inside_parens.append(item)
    else:
        inside_parens.append(item.split("(")[0])
...

What would be a better approach?

>>> s = 'Person One (Something inside here) Second Thing (another thing) OK (something else)'
>>> import re
>>> re.sub('(.*?) \((.*?)\)( ?)', r'\2 (\1)\3', s)
'Something inside here (Person One) another thing (Second Thing) something else (OK)'

The way in which whitespace needs to be not switched around makes it a tad uglier, but it's not a very bad regular expression.
