Anyone experienced with interpreted high-level languages knows this is not true. Not because iterating a sequence is expensive, but because the interpreter is constantly executing the body of the loop. There is a reason why Matlab and Python/NumPy programmers rely heavily on vectorized array expressions for efficient numerics. The only thing more evil than a for-loop is recursive function calls. This does not mean Python is slow. It just means you have to program differently. -- http://mail.python.org/mailman/listinfo/python-list
