Changed form of dict creation to work under Python 2.6

This form of dict creation wasn't working for me anyway with Python 2.6.  Does work with Python 2.7.

    a = {key:var for key,var in [('one', 1), ('two', 2)]}

Shifted to a different stye that work under 2.6.

    a = dict((key,var) for key,var in [('one', 1), ('two', 2)])

Kindest regards,
Tim
