Two things.   You really shouldn't shadow a builtin with your own
 locals,  though it hasn't hurt you this time. Next time pick a
 different name than dict.

Your real problem is that you're trying to iterate over items, 
 but forgot to use that method. The for loop line should
 end

                 in dict.items () :


You may be confused,  since it's different in python 3.x
