Random [-x..x] && !NULL

Fellow Progs,
any idea to nicely implement this ?

First idea...ugly

get random value
if value is zero
  get random value
done

Second idea

get random positive value
make coin toss
if coin shows head
  value *= -1

But there must be something easiert / nicer

thanks alot.

from random import randrange
def randrange_nonzero(x, y):
    n = randrange(x, y-1)
    return n + (not n)
