I agree with you that list extending is faster way to add as compared to method 1. also that method 2 is mapped to 'extend()' anyway, but why is the method 3 ( l3.extend() ) in my example code talking only nearly 1% of time to complete as compared to method 1/2??? I think there is a problem with the code but i don't see where. :-( > Terry J. Reedy Thanks Terry for yet another small (really small) step towards enlightment.
