- I know it has the name "format_list", but is it really intended to require a
list? Why not a sequence, or a collection, or an iterable? I would think it would be fine to pass an iterable to traceback.format_list. Is it fine?
In 3.4, format_list() was documented to accept return values of extract_tb() and extract_stack() functions and they both were returned lists:
def extract_tb(tb, limit=None): return list(_extract_tb_iter(tb, limit=limit))
def extract_stack(f=None, limit=None): stack = list(_extract_stack_iter(_get_stack(f), limit=limit)) stack.reverse() return stack
I don't think we support the "pass manually created iterables" case here.
- What is the desired component type for the aggregate passed to
format_list? In 3.4-and-earlier it was Tuple[str, int, str, Optional[str]], and that still works in 3.5-through-3.8, but is that just backwards compatibility [...]
Yes, the old API is still supported for backwards compatibility reasons.
