More feedback:

In Riddle 2, the "global" declarations are unnecessary, as you are
only referencing the globally-defined vars for read.

Also in Riddle 2, I would replace
    for s in alphabet: indices[s] = alphabet.index(s)
with
    indices = dict( (s,i) for i,s in enumerate(alphabet) )

(I see part of your Python Challenge as giving new Pythoners something
to cut their teeth on, and so this is an opportunity for giving
examples of good style.)

I do enjoy these challenges, they are quite addicting. :)
