Ezio Melotti <ezio.melo...@gmail.com> added the comment: set.union doesn't change the first set (i.e. a), but returns a new sets (i.e. c): >>> def func(): ... a = set([0]) ... a.pop() ... print 'a:', a ... b = set([1, 2]) ... c = a.union(b) ... print 'a:', a ... return c ... >>> func() a: set([]) a: set([]) set([1, 2])
