But, of course, the reason to avoid lambda is that you avoid a place to
make your code clearer.  A much better choice in this case is:

     def compare_cities(name_city1, name_city2):
         return cmp(name_city1[1], name_city2[1])

     name_city_sort(compare_cities)

Of course I believe a coming feature will eventually do what you want in
a completely different way:

     def getcity(name_city):
         return name_city[1]

     name_city_list.sort(key=getcity)
