And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...ends up being like:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

& ⤴️ ❎ ➕ 🇨🇻 ❌ `hashed_password=hashed_password`, 💖:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...🔚 🆙 💆‍♂ 💖:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```
