Python Packaging

In Brevvie Python + AI — Section 1: Setup Your IDE, Python Packaging begins with a simple but important step: turning a folder of scripts into a package by adding __init__.py.

Key points from the source

• calc/ becomes a package when calc/__init__.py exists.
• __init__.py can be empty, but can also re-export a simpler public API.
• Re-exports let callers use from calc import ... instead of importing from deeper internal files.

Why it matters

The lesson uses packaging to show the jump from one-off scripts to reusable code.
