I resisted my urge to use a regexp and came up with this:

>>> from itertools import groupby
>>> s = 'apple=blue+cart'
>>> [''.join(g) for k,g in groupby(s, lambda x: x in '=+')]
['apple', '=', 'blue', '+', 'cart']
>>>

For me, the regexp solution would have been clearer, but I need to
stretch my itertools skills.
