Here's the `user.py` file with Pydantic schemas for user in the `app/api/v1/schemas/` directory:

from typing import Optional
from pydantic import BaseModel, EmailStr

class UserBase(BaseModel):
    email: EmailStr
    is_active: Optional[bool] = True
    is_superuser: bool = False
    full_name: Optional[str] = None

class UserCreate(UserBase):
    password: str

class UserUpdate(UserBase):
    password: Optional[str] = None

class UserInDBBase(UserBase):
    id: Optional[int] = None

    class Config:
        orm_mode = True

class User(UserInDBBase):
    pass

class UserInDB(UserInDBBase):
    hashed_password: str

Explanation:

1. We import the necessary modules: `typing` for type hints, `pydantic` for defining data models, and `EmailStr` from `pydantic` for email validation.
