* 🚨 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.

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।
