"correct" being a synonym for "as I expect" ;)

I'll second Ben's recommendation of Python 3:

>>> t = "mäßig", "müßig", "nötig"
>>> print(t)
('mäßig', 'müßig', 'nötig')
>>> print(*t)
mäßig müßig nötig
>>> print(*t, sep=", ")
mäßig, müßig, nötig

All three variants also work with files. Example:

>>> with open("tmp.txt", "w") as outstream:
...     print(*t, file=outstream)
... 
>>> open("tmp.txt").read()
'mäßig müßig nötig\n'


Should you decide to stick with Python 2 you can use a helper function:

>>> t = u"mäßig", u"müßig", u"nötig"
>>> def pretty_tuple(t, sep=u", "):
...     return sep.join(map(unicode, t))
... 
>>> print pretty_tuple(t)
mäßig, müßig, nötig
>>> print pretty_tuple(t, sep=u" ")
mäßig müßig nötig
