[New-bugs-announce] [issue37178] One argument form of math.perm()

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

The perm() function should have a one argument form and change its signature to ``perm(n, k=None)``.  This matches what itertools:

itertools.permutations(iterable, r=None)
   Return successive r length permutations of elements
   in the iterable.

   If r is not specified or is None, then r defaults to
   the length of the iterable and all possible full-length
   permutations are generated.
