use split on the list to split it up. search each element for something like:

if '"' == element[:-1]:

if that evaluation is True, I would remove the quote mark from the word on the right side, and place a new one on the left side using something like '"' + element.

I would do the same thing for the other side in the same for loop, instead the evaluation would be:

if '"' == element[:1]:
