I just wondered if something smoother was available.
In terms of behaviour and 'safety', I'd go for:
rec = { 'code1': '1,2,3', 'code2': '' }
next(csv.reader([rec['code1']]))
['1', '2', '3']
next(csv.reader([rec['code2']]))

.split, possibly, although there will be problems if the string contains

str.join is a many-to-one function, and so it doesn't have an inverse.
You can't always get the input back unchanged:
L = [a, b, c|d, e]
s = '|'.join(L)
