Here's the `user.py` file with Pydantic schemas for the `User` model, which you can place in the `app/api/v1/schemas/` directory:

from typing import Optional
from pydantic import BaseModel, EmailStr

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

class UserCreate(UserBase):
    email: EmailStr
    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 UserInUpdate(UserUpdate):
    pass

This file defines several Pydantic models for the `User` model:



Note: This code assumes that you have the `pydantic` library installed and that your project follows the recommended structure for FastAPI applications using SQLAlchemy and SQLite.
