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.

def randnot0(x): return randint(-x, x) or randnot0(x)
