> Do you know if this generates a new list internally (memory consumption?) It does not. That parenthesized expression is a called generator expression. It compiles to a small subroutine, more or less, that gets invoked repeatedly as you iterate through it. A similar expression with square brackets is called a list comprehension and does generate a new list. -- http://mail.python.org/mailman/listinfo/python-list
