If one writes X = partial.skip, it looks quite nice:
split_one = partial(str.split, X, 1)
Or even
_ = partial.skip split_one = partial(str.split, _, 1)
Or even
… = partial.skip split_one = partial(str.split, …, 1)

That won't work:
... = 1 File "<stdin>", line 1 SyntaxError: can't assign to Ellipsis
Like None/True/False, "..." is a constant that can't be modified (you can assign to the *name* Ellipsis, but the "..." syntax will always refer to the specific object).

It does, but they may not contain characters of the category "Punctuation, other":
import unicodedata unicodedata.category("…") 'Po'
