join string lists

Assuming that if you only pass a list with one item it returns an empty list.

from string import ascii_uppercase


def adjacent_list(iterabe):
    stored_character = None
    for character in iterabe:
        if stored_character:
            yield ''.join((stored_character, character))
        stored_character = character


for index in range(1, 27):
    letters = (ascii_uppercase[:index])
    print(list(adjacent_list(letters)))

Output:[]
['AB']
['AB', 'BC']
['AB', 'BC', 'CD']
['AB', 'BC', 'CD', 'DE']
