[dyhawks]

email: Optional[str] = Query(..., description="email", min_length=10, max_length=50,regex="^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$")

result

{
    "detail": [
        {
            "loc": [
                "query",
                "email"
            ],
            "msg": "string does not match regex \"^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\\.[a-zA-Z0-9_-]+)+$\"",
            "type": "value_error.str.regex",
            "ctx": {
                "pattern": "^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\\.[a-zA-Z0-9_-]+)+$"
            }
        }
    ]
}

"msg": "string does not match regex \"^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\\.[a-zA-Z0-9_-]+)+$\""
I think it's ugly

You can use EmailStr from Pydantic:
