This is easier to do with a generator comprehension and join method:
s = '\n'.join(str(item[0]) + str(item[1]) for item in done)

There is a builtin function enumerate for this case, IMHO it's slightly
easier to read:
for i, item in enumerate(s)
x = item[0]
...
if not i%2:

It's a personal matter, but usually python programmers treats values in
boolean context directly without comparison:
if done and not beensaved and askyesno(...):
The rules are documented here: http://docs.python.org/lib/truth.html .
