If your data is a list, then it will be a list in the dict.  You could
just make it so that particular key always contains a list of
characteristics, even if it's a list of only one.

>>> data = 'Canadian, Pub Food'.split(',')
>>> data
['Canadian', ' Pub Food']
>>> data = 'French'.split(',')
>>> data
['French']

Then just put the list as the value.

d['characteristics'] = data
>>> data = 'Canadian, Pub Food'.split(',')
>>> d['characteristics'] = data
>>> d['characteristics']
['Canadian', ' Pub Food']
