just for fun, here is one way to do it with a listcomp. Obfuscated
python fans, rejoice!

>>> alpha = 'abcdefghijklmnopqrstuvwxyz'
>>> for i, digraph in enumerate(sorted([''.join((x, y)) for x in alpha \
    for y in [''] + [z for z in alpha]], key=len)):
...     locals()[digraph] = i + i
...
>>> a
1
>>> b
2
>>> ac
29
>>> dg
111
>>> zz
702
>>> 26**2 + 26
702
