Right, the main correspondence here is with "sum()": folks can't write "sum(a, b, c)", but they can write "a + b + c".
The various container constructors are also consistent in only taking an iterable, with multiple explicit items being expected to use the syntactic forms (e.g. [a, b, c], {a, b, c}, (a, b, c))
The same rationale holds for any() and all(): supporting multiple positional arguments would be redundant with the existing binary operator syntax, with no clear reason to ever prefer one option over the other.
Isn't there a difference, though, insofar as we don't have a '+/sum' or 'and/all' equivalent of [a, b, *c]? You need to write 1 + 3 + sum(xs), or a and b and all(ys). Or, of course, any(chain([a], [b], c)), but that is not pretty. Clément.
