[python] How do I find the difference between two values without knowing which is larger?

Although abs(x - y) or equivalently abs(y - x) is preferred, if you are curious about a different answer, the following one-liners also work:

  • max(x - y, y - x)

  • -min(x - y, y - x)

  • max(x, y) - min(x, y)

  • (x - y) * math.copysign(1, x - y), or equivalently (d := x - y) * math.copysign(1, d) in Python =3.8

  • functools.reduce(operator.sub, sorted([x, y], reverse=True))
