Thanks. Yes, that it is what I was trying to get at. But I didn't know the correct wording. :) Here is 'var.extend(["a"])' added to the simple timeit comparison: >>> import timeit >>> timeit.timeit(stmt='var += ["a"]', setup='var = []', number=100000000) 6.978962032000709 >>> timeit.timeit(stmt='var.extend(["a"])', setup='var = []', number=100000000) 6.58610403899911 >>> timeit.timeit(stmt='var.append("a")', setup='var = []', number=100000000) 1.8816217469993717 Collin
