Hi, I initially thought that generator/generator expression is cool(sort of like the lazy evaluation in Haskell) until I notice this side effect.
>>>a=(x for x in range(2)) >>>list(a) [1,2] >>>list(a) [] Would this make generator/generator expression's usage pretty limited ? As when the program/system goes beyond a single module, this behaviour can cause subtle bugs ? -- http://mail.python.org/mailman/listinfo/python-list
