* 🚨 Tránh sử dụng `Optional[SomeType]`
* Thay vào đó ✨ **sử dụng `Union[SomeType, None]`** ✨.

Cả hai là tương đương và bên dưới chúng giống nhau, nhưng tôi sẽ đễ xuất `Union` thay cho `Optional` vì từ "**tùy chọn**" có vẻ ngầm định giá trị là tùy chọn, và nó thực sự có nghĩa rằng "nó có thể là `None`", do đó nó không phải là tùy chọn và nó vẫn được yêu cầu.

Tôi nghĩ `Union[SomeType, None]` là rõ ràng hơn về ý nghĩa của nó.

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

Both are equivalent and underneath they are the same, but I would recommend `Union` instead of `Optional` because the word "**optional**" would seem to imply that the value is optional, and it actually means "it can be `None`", even if it's not optional and is still required.

I think `Union[SomeType, None]` is more explicit about what it means.

#### `Union` oder `Optional` verwenden?

Wenn Sie eine Python-Version unterhalb 3.10 verwenden, hier ist mein sehr **subjektiver** Standpunkt dazu:

* 🚨 Vermeiden Sie `Optional[SomeType]`
* Stattdessen ✨ **verwenden Sie `Union[SomeType, None]`** ✨.

উভয়ই সমতুল্য এবং মূলে একই, কিন্তু আমি `Union`-এর পক্ষে সুপারিশ করব কারণ "**অপশনাল**" শব্দটি মনে হতে পারে যে মানটি ঐচ্ছিক,অথচ এটি আসলে মানে "এটি হতে পারে `None`", এমনকি যদি এটি ঐচ্ছিক না হয়েও আবশ্যিক হয়।

আমি মনে করি `Union[SomeType, None]` এর অর্থ আরও স্পষ্টভাবে প্রকাশ করে।

`PushContext` is built up by querying the above layers. For some simple use cases, this is as simple as storing something like `configstore.List(SomeType)`; in this case, the only difference from directly exposing the configstore is to snapshot the current state. In other cases, some pre-computations and indexes are computed to make later accesses efficient.
