Thanks Diez for your explanation.
The problem with tuples is that it is not easy to modify them: in my case, I
need to append a string to the tuple at each recursive step.
So, it seems to me that I need to write a loop to modify the tuple, because
on a simple example:
>>> a=("foo", "bar")
(u'foo', u'bar', u'toto')
I do not find any other means to obtain that result for b. With lists, I can
Am I right?
python -c "print ''.join([chr(154 - ord(c)) for c in '*9(9&(18%.\
