Give me a Python program to print import pprint given the following:
I wrote the below code

    def descend_and_check(iterable, level=0):
        if isinstance(iterable, Mapping):
            assert isinstance(iterable, syaml_dict)
            return descend_and_check(iterable.values(), level=(level + 1))
        max_level = level
        for value in iterable:
            if (isinstance(value, Iterable) and (not isinstance(value, str))):
                nlevel = descend_and_check(value, level=(level + 1))
                if (nlevel > max_level):
                    max_level = nlevel
        return max_level
    specs = ['mpileaks    ^zmpi', 'dttop', 'dtuse']
    for spec in specs:
        dag = Spec(spec)
        dag.normalize()
        from pprint import pprint
        pprint(dag.to_node_dict())
        break
        level = descend_and_check(dag.to_node_dict())
        assert (level >= 5)

What's a good function header?
