Sorry, missed an option in there:
> def get_word(s, which=1, sep=','):
> return s.split(sep)[which-1].strip()
>
> >>>
> >>> get_word('bread, butter, milk')
> 'milk'
>
> >>>
>>> get_word('bread, butter, milk')
'bread'
>>> get_word('bread, butter, milk', 3)
'milk'
>>> get_word('bread is brown, butter is yellow, milk is white')
'bread is brown'
>>> get_word('bread is brown, butter is yello, milk is white', 3)
'milk is white'
