Simplify hn() function

The new form:

- Avoids the unnecessary range() call. On Python 2 this avoids building
  the data structure in memory.
- Avoids the try/except block. The comparison is required either way, so
  just do that from the start.
- Always explicitly return as a value. The old form sometimes fell
  through and returned None.

The new version is also slightly faster. Running the function through
Python's timeit showed the following results:

old: 0.6434267910080962
new: 0.40665965899825096
