* 🚨 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.

* 🚨 `Optional[SomeType]` ব্যবহার এড়িয়ে চলুন।
* এর পরিবর্তে ✨ **`Union[SomeType, None]` ব্যবহার করুন** ✨।

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।

* 🚨 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.
