This is an excellent observation and points to the real problem with the
original question. The problem is that the base class has more features
than some of the classes that will be dervied from it which is usually
just plain wrong.

I got over my intimidation with tokenize and learned to use it to strip
comments from code files. In the process, I learned that the tuples
that it returns for the position in the code of various tokens is
1-based in the row rather than 0-based, so the tuple pair (3,1),(3,2)
would be the start
Does anybody else ever run into the case of using enumerate on a slice
but then wish that the original list indices were being returned
instead of the ones starting at zero?
I would like to see an offset argument that could be used with
enumerate:
###
l=range(5)
for i,li in enumerate(l[3:]):
I found a work around for the terminal it appears that the message in
the input("message") was being assigned to the next variable making
Matrix=error=alpha
It's good to see that you got this working. Just a couple notes:
1) Regarding your comment above, it just *looks* like it was doing an

I'm able to use the built in XML parser to effect "normal" XML parsing usage
but frequently, I'm not doing anything to complicated and would simply like to
translate the XML file into a more "Pythonic" structure. What's the best way
to do this? Something from the standard libraries would be pr

The reason that new_alph never changes is that you are calculating

The former: 3 on each side. Exactly 3.
BTW , you can check your understanding by saving the image you
get from riddle 6, compressing it with zlib, filtering out all but
