.. function:: cmp_to_key(func)
- Transform an old-style comparison function to a key-function. Used with
- tools that accept key functions (such as :func:`sorted`, :func:`min`,
- :func:`max`, :func:`heapq.nlargest`, :func:`heapq.nsmallest`,
- :func:`itertools.groupby`).
- This function is primarily used as a transition tool for programs
- being converted to Py3.x where comparison functions are no longer
- supported.
-
- A compare function is any callable that accept two arguments, compares
- them, and returns a negative number for less-than, zero for equality,
- or a positive number for greater-than. A key function is a callable
- that accepts one argument and returns another value that indicates
- the position in the desired collation sequence.
