frequency (descending), then by name (ascending). To

sure! just return the composite key as a tuple:
# sort on descending count, ascending name
deco = sorted(freq.items(), key=lambda x: (-x[1], x[0]))
(when comparing tuples, Python first compares

I'm interested to learn how more experienced Python folks would solve
this little problem.
I think I'd do the following:
from collections import defaultdict
names = freddy fred bill jock kevin andrew kevin kevin jock
freq = defaultdict(lambda: 0)
for name in

and the -x hack above to
achieve a descending sort feels a bit odd to me, though I couldn't think
of a better way to do it.
The other way would be to pass a custom comparison callback to sort,
