Hi!
If I have a list of IDs and a hash which maps
each ID to a name:
ids=[1, 2, 3, 4]
names={
1: "foo",
2: "bar",
...}
I can't do the following:
def mycmp(a, b):
return cmp(names[a], names[b])
ids.sort(mycmp)
since "name" is unkown in mycmp.
What's the best solution?
What about giving the sort function a third argument?
def mycmp(a, b, names):
return cmp(names[a], names[b])
ids.sort(mycmp, names)
