code pattern to test if list has all the same

[Skaperen]

yes, that does make all() statically faster and the choice for speed. i can see how it behave for an empty list, now. it sets some variable to True and looks for the first False. if none found, it leaves it as True which might be the answer needed in dome cases. and if not, just test for empty first. an empty list comes across as False as a boolean.
