Well, without some sample code showing what you are trying, it is
difficult to say what you have missed. How would I do it?

[code]
returned_data = [(u'string 1', u'string 2', u'string 3', u'string 4',
u'string 5', u'string6', u'string 7')]
strings_tuple = returned_data[0]
individual_string = strings_tuple[0]
for txt in strings_tuple:
    print txt
[/code]

My guess is that you are dereferencing from the list incorrectly. If
you don't want to use intermediate variables this should work:

[code]
returned_data = [(u'string 1', u'string 2', u'string 3', u'string 4',
u'string 5', u'string6', u'string 7')]

for txt in returned_data[0]:
    print txt
[/code]
