This is because .findall method is returning a 'list' object and therefore doesn't have a .groupdict method
findall = re.findall(r'(?P<twitter>@[\w\d]+)$', string, re.I|re.M)
# ['@kennethlove', '@chalkers', '@davemcfarland', '@joykesten']
type(findall)
# <class 'list'>
On the other hand, .search method returns 're.Match' object that has the 'groupdict' method included
search = re.search(r'(?P<twitter>@[\w\d]+)$', string, re.I|re.M)
# <re.Match object; span=(66, 78), match='@kennethlove'>
type(search)
<class 're.Match'>
Don't forget that you could always use dir() function to check what kind of attributes or methods your variables got inside
dir(search)
# ['__class__', '__copy__', '__deepcopy__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'end', 'endpos', 'expand', 'group', 'groupdict', 'groups', 'lastgroup', 'lastindex', 'pos', 're', 'regs', 'span', 'start', 'string']
