It would help if you explained what you want the contents of the list
to be, why you want a list as opposed to a tuple or a generator or
whatever ... we can't be expected to imagine why getting groups as
tuples is "sort of a problem".

Use a concrete example, e.g.

>>> import re
>>> regex = re.compile(r'(\w+)\s+(\d+)')
>>> text = 'python 1 junk xyzzy 42 java 666'
>>> r = regex.findall(text)
>>> r
[('python', '1'), ('xyzzy', '42'), ('java', '666')]
>>>
