[Tutor] beginning encryption

[Roger Lea Scherer]

I am absolutely stumped. I've tried a number of different scenarios and
copied the answer more than I like, but I still can't figure this out. I
don't want to copy the answer verbatim because then I won't learn.

I'm doing the beginning cipher, mix up the letters routine. I get the
entire Gettysburg address with no alterations in this form of the code (and
a few others I've tried). I do not receive any error, but I expect the
character in the Gettysburg address to change to the index position in the
encryption variable.

What am I not getting?

Thank you as always.



address = """Four score and seven years ago our fathers brought forth on
this continent, a new nation,
conceived in Liberty, and dedicated to the proposition that all men are
created equal.
Now we are engaged in a great civil war, testing whether that nation, or
any nation so conceived
and so dedicated, can long endure. We are met on a great battle-field of
that war. We have come
to dedicate a portion of that field, as a final resting place for those who
here gave their lives that
that nation might live. It is altogether fitting and proper that we should
do this.
But, in a larger sense, we can not dedicate -- we can not consecrate -- we
can not hallow -- this ground.
The brave men, living and dead, who struggled here, have consecrated it,
far above our poor power
to add or detract. The world will little note, nor long remember what we
say here, but it can never
forget what they did here. It is for us the living, rather, to be dedicated
here to the unfinished work
which they who fought here have thus far so nobly advanced. It is rather
for us to be here dedicated
to the great task remaining before us -- that from these honored dead we
take increased devotion
to that cause for which they gave the last full measure of devotion -- that
we here highly resolve
that these dead shall not have died in vain -- that this nation, under God,
shall have a new birth
of freedom -- and that government of the people, by the people, for the
people, shall not perish
from the earth."""
