const email = "[email protected]";

__all__ (Controlling Exports)

PY · Modules & Imports
Syntax
__all__ = ['name1', 'name2']
Example
# utils.py
__all__ = ["format_price", "validate_email"]

def format_price(amount: float) -> str:
    return f"${amount:,.2f}"

def validate_email(email: str) -> bool:
    return "@" in email

def _internal_helper():  # not exported
    pass

Note __all__ defines what 'from module import *' exports. It does not prevent direct imports of unlisted names. Prefix internal helpers with underscore by convention.
