Unless you need holder and held for something else, all of the above can
be replaced with
distqtydic = dict( (key, len(value)) for key, value in
sorted(dictionary.items())

The problem is that you are trying to add 1 to a value that is not
defined yet. You can either make
count=defaultdict(int)
or write
count[item] = count.get(item, 0) + 1
If this is the only use of distqtydic then even the shortened code above
is more than you need, you could just write
for item in dictionary.values():
count[len(item)] += 1 # assuming defaultdict

No need for the intermediate k, v; just use the names you like.
