i use:

void swap(T)(ref T a, ref T b) {
   T t = a;
   a = b;
   b = t;
}

int a = 1;
int b = 2;
swap(a,b);

Or multiple return values, and then:

a, b = b, a;

I don't know where that syntax came from, but but I'm pretty sure it 
predates python by a good bit.  Probably Ada or something.

Ada doesn't have multiple assignment.  CLU had it in 1974, though.
