Fields - Pydantic

exclude=True and repr=False is a good pydantic combination for secret attributes such as user passwords, or hashed passwords. exclude keeps it out of model_dumps, and repr keeps it out of the logs.






        
from pydantic import BaseModel, Field


class User(BaseModel):
    name: str = Field(repr=True)  
    age: int = Field(repr=False)


user = User(name='John', age=42)
print(user)
#> name='John'
