>>> s =
'1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>> size = 10
>>> print '?\n'.join([s[i:i+size] for i in xrange(0, len(s)+1,
size)])
1234567890?
abcdefghij?
klmnopqrst?
uvwxyzABCD?
EFGHIJKLMN?
OPQRSTUVWX?

Just adjust "size" to 100 rather than 10.
It may be a bit brute-force-ish, and there may be other more
elegant ways that I don't know, but that list comprehension
extracts pieces of "s" of size "size" and creates a list where
each piece doesn't excede "size" characters. The join() then
just smashes them all together, joined with your requested
"quotation-mark followed by newline"
And for the regexp-junkies in the crowd, you can use
>>> import re
>>> r = re.compile("(.{%i})" % size)
>>> print r.sub(r"\1?\n", s)
1234567890?
abcdefghij?
klmnopqrst?
uvwxyzABCD?
EFGHIJKLMN?
OPQRSTUVWX?

I'm sure there are plenty of other ways to do it. :)
