Explain what the term 'packet' means in the context of programming in Python.

In Python, a package is a way of organizing modules into a hierarchical directory structure. A package is a directory that contains an __init__.py file (which is optional in newer versions of Python but often used for package initialization). Packages allow related modules to be grouped together to avoid name conflicts and improve project structure.

For example, the structure:

my_package/
    __init__.py
    module1.py
    sub_package/
        __init__.py
        module2.py

Allows importing modules like:

from my_package import module1
from my_package.sub_package import module2

Thus, a package is a way to logically group modules into a convenient structure.
