It is a combination of factors. 1) Every time you access gen.next you create a new method-wrapper object. 2) Typing an expression at the interactive prompt implicitly assigns the result of the expression to the variable '_' 3) When the method-wrapper is destroyed the memory becomes available to be reused the next time a method-wrapper (or other object of similar size) is created. So in fact you have 6 different objects produced by your 6 accesses to gen.next although (since you never have more than 3 of them in existence at a time) there are probably only 3 different memory locations involved. -- http://mail.python.org/mailman/listinfo/python-list
