What is a package in Python?

A package in Python is a collection of modules organized in directories that allows you to structure your Python code into a hierarchical manner. Packages can contain sub-packages and modules, making it easier to organize large codebases.

# Directory structure
# my_package/
#     __init__.py
#     module1.py
#     module2.py

# Importing a module from a package
from my_package import module1
module1.some_function()

The __init__.py file in a package directory indicates that the directory should be treated as a package. It can also contain initialization code for the package.

Using packages allows you to group related modules together, making your code more modular, maintainable, and easier to navigate.
