How can I use Pydantic to manage environment variables in my application?

You can use Pydantic's BaseSettings class to easily manage environment variables. It allows you to define settings as class attributes.

Can you show me a simple example of how to implement this?

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 should I include in the .env file?

In the .env file, you should include key-value pairs for the variables you defined in your Settings class, like this:

APP_NAME='My Application'
ADMIN_EMAIL='[email protected]'

Can I validate the environment variables with Pydantic?

Yes, Pydantic automatically validates the environment variables based on the types you defined in your Settings class.
