comparing dictionaries

Hello,

> {'001' : '01'}
>
> The second dict's contents are like this with a tuple instead of a

> {('This is one', '001'): '01'}

> Pseudo Code:

>    # How do I do the following line?
>    if key not in second_dict or if it is, but has has the wrong value,
> then let me know
def cmp_dicts(first, second):
    return sorted(first.iteritems()) == \
           sorted(((k[1], v) for k, v in second.iteritems()))
