The situation here is a known and could be corrected by changing the meaning of list comprehension, for instance by having [x for x in iterable] to be an alias for list(x for x in iterable). In such a way the StopIteration exception would be always swallowed and there would be consistency with generator expressions (by construction). However, the list comprehension would become non-equivalent to the corresponding for-loop with an .append, so somebody would be un happy anyway :-/ -- http://mail.python.org/mailman/listinfo/python-list
