Sometimes it is known in advance, that the time spent in a loop will be in order of minutes or even hours, so it makes sense to optimize each element in the loop to make it run faster. One of instructions which can sure be optimized away is the check for the break condition, at least within the time where it is known that the loop will not reach it.
Any idea how to write such a loop? e.g. counter = 2*64 while counter(BUT DON'T CHECK IT THE FIRST ONE HOUR LONG): ... do something ... # and decrease the counter Thanks for any hint, but in particular if related to timers on the Windows 2000/XP system I am mainly working with. What do you think about this idea? Does it make sense? Claudio Grondi -- http://mail.python.org/mailman/listinfo/python-list
