What is the difference between a module and a package in Python.?

In Python, a module is a single file that contains Python definitions and statements. It typically consists of functions, classes, and variables that can be imported and used in other Python codes. A module can be considered a reusable library that provides a set of functionality to a program.

On the other hand, a package is a collection of related Python modules that are organized in a directory hierarchy. A package is a way of structuring Python modules so that they can be easily imported and used by other modules or programs. A package can contain sub-packages and modules, which can also contain sub-packages and modules, forming a hierarchical structure.

To create a package, you need to create a directory that contains a __init__.py file. This file is used to mark the directory as a Python package, and it can contain code that will be executed when the package is imported.

The main difference between a module and a package is that a module is a single file, while a package is a directory that can contain multiple Python modules and sub-packages. A module can be imported directly using its filename, while a package must be imported using its package name, followed by the module or sub-package name separated by dots.

For example, suppose you have a package called mypackage that contains two modules called module1 and module2. You can import these modules using the following statements:

import mypackage.module1
import mypackage.module2

Alternatively, you can import these modules using the from keyword, like this:

from mypackage import module1, module2

In summary, a module is a single file that contains Python code, while a package is a collection of related modules and sub-packages that are organized in a directory hierarch
