The dictionary type is specifically not required to provide its elements in
any order!

Rather than using a dictionary and then (presumably) a while loop until the
dictionary is empty, consider setting up a list or tuple of tuples, such as

    links = (('index.html', 'Home'), ('file0.html', 'Some foo'))

The you can use

    for link, caption in links:
        # generate nav bar line from link and capion
