The initial string looks like it's close enough to the CSV format.
Unfortunately Python's csv module operates on files, not strings -- to 
use it you have to wrap the string into a stream:

 >>> import csv
 >>> import io
 >>> next(csv.reader(io.StringIO('"ab,c" , def')))
['ab,c ', ' def']


Apply str.strip() on every part to remove leading and trailing whitespace:


 >>> def mysplit(s):
	return [part.strip() for part in next(csv.reader(io.StringIO(s)))]

 >>> mysplit('"ab,c" , def')
['ab,c', 'def']
