sorting a dictionary

[user at domain.invalid]

Suppose I have dictionary (associative arry) with people's names and
ages, like

     names = {"Bob":27, "Larry":35, "Curly":65, "Moe":66, "Jeff":31,
              "Guido":34, "Parrot":36}

How can I sort this? And what does the method "names.keys().sort()"
actually do?
