4.3.3 Package Structure and init.py
A package is a directory that groups related modules.
Packages help organize large codebases into logical hierarchies.
Package Structure
A typical package:
- Is a directory
- Contains multiple module files
- May include an
__init__.pyfile
Packages support hierarchical imports and namespace management.
Role of init.py
The __init__.py file:
- Marks a directory as a package
- Can initialize package-level code
- Controls what is exposed during imports
📌 Note:
Well-structured packages improve scalability and code clarity.
