# error: Unexpected '...' [misc]
tuple_2_err: tuple[str, ...] = ("b", "c")
# error: Unexpected '...' [misc]
# error: Dict entry 0 has incompatible type "str": "Tuple[str, str, str]"; expected "str": "Tuple[str, Any]" [dict-item]
tuple_3_err: tuple[str, ...] = ("b", "c", "d")
dict_with_tuple_1: dict[str, tuple[str, str, str]] = {"a": ("b", "c", "d")}
# error: Unexpected '...' [misc]
dict_with_tuple_2_err: dict[str, tuple[str, ...]] = {"a": ("b", "c")}

tuple_20: Tuple[str, ...] = ("b", "c")
tuple_30: Tuple[str, ...] = ("b", "c", "d")
dict_with_tuple_10: dict[str, Tuple[str, str, str]] = {"a": ("b", "c", "d")}
dict_with_tuple_20: dict[str, Tuple[str, ...]] = {"a": ("b", "c")}
dict_with_tuple_30: dict[str, Tuple[str, ...]] = {"a": ("b", "c", "d")}Expected Behavior
I've expected that tuple and typing.Tuple works the same and errors will not occurs.
Actual Behavior
Standard tuple have got error: Unexpected '...' [misc]

Dupe of #7907
Jasha10 commentedon Nov 8, 2021
The linked issue #7907 reports that this issue was solved by PR #9564, but I find that this is still an issue in mypy version 0.910:
Should we reopen this issue? Or should I file a new one?

This has been fixed on master for a long time, try
pip install -U git+git://github.com/python/mypy.git.This issue tracks the 0.920 release: #11158
Unfortunately, the people with the ability to push the release over the line have been really busy.
