What is meant by the term 'package' in the Python programming language?

In Python, a package is a way of organizing modules into a hierarchical directory structure. A package is a directory containing an __init__.py file (in Python 3.3+, this file is not mandatory but recommended for compatibility), which indicates that the directory is a package.

Packages allow grouping related modules and subpackages, simplifying management of large codebases and providing convenient imports.

Example of a package structure:

my_package/
├── __init__.py
├── module1.py
└── sub_package/
    ├── __init__.py
    └── module2.py

Importing from a package:

from my_package import module1
from my_package.sub_package import module2

Thus, a package is a directory with modules and (optionally) subpackages, serving for logical organization of code in Python.
