How can I manage settings in my Python application using Pydantic?

You can use Pydantic's BaseSettings class to manage application settings easily. It allows you to define settings as Python classes.

Can you show me a simple example of how to use BaseSettings?

Sure! Here's a basic example:

from pydantic import BaseSettings

class Settings(BaseSettings):
    app_name: str
    admin_email: str

    class Config:
        env_file = '.env'

settings = Settings()
print(settings.app_name)

What if I want to load settings from a JSON file instead of an environment file?

You can override the Config class to specify a different file format. For JSON, you can read the file and pass the data to the Settings class.

Is it possible to validate the settings values?

Yes, Pydantic automatically validates the values based on the types you define in your settings class.
