issue closedArjanCodes/2021-command-undo-redo

not understanding the use of `dict` instead of `typing.Dict`

Hello Arjan, thanks for all the detailed explanation in the video about the command pattern.

Just trying to run this program, but when I hit lines like:

@dataclass
class Bank:
    accounts: dict[str, Account] = field(default_factory=dict)

will produce TypeError: 'type' object is not subscriptable with Python 3.8.5

Commonly we may do it this way:

from typing import Dict

@dataclass
class Bank:
    accounts: Dict[str, Account] = ...

Could you please elaborate more on:
what is special about the dict being used here, that makes it act like typing.Dict?
