You wrote a program to find the two smallest ints that would have a hash collision in the CPython set implementation?  I'm impressed.  And by impressed I mean frightened. ? print set([0,8]).pop(), set([8,0]).pop()

If 'smallest ints' means the sum of the absolute values then these are slightly smaller:

print set([-1,6]).pop(), set([6,-1]).pop() 6 -1
