I see three options. You can (1) use a list comprehension [add_all_elements(*sub) for sub in alist] (2) replace map() with itertools.starmap() list(itertools.starmap(add_all_elements, alist)) (3) change your function's signature from add_all_elements(*args) to add_all_elements(args), either by modifying it directly or by wrapping it into another function list(map(lambda args: add_all_elements(*args), alist)) (3a) My personal preference would be to change the signature and then use the list comprehension def add_all_elements(args): ...
