Answer 1

You could do it like this in Python 2.x:

>>> l = ((1,2),(3,4))
>>> dict(map(lambda n: (n[0], unicode(n[1])), l))
{1: u'2', 3: u'4'}

or in Python 3.x:

>>> l = ((1,2),(3,4))
>>> {n[0] : str(n[1]) for n in l}
{1: '2', 3: '4'}

Note that strings in Python 3 are the same as unicode strings in Python 2.
