4.3 Modules and Packages

In Python, modules and packages are a way of organizing larger projects, making them easier to manage and understand. When developing complex software, it is often necessary to break it down into smaller, more manageable components. Modules and packages provide a convenient way of doing this by allowing developers to group related code together in a logical way.

Modules, which are individual Python files, can contain functions, classes, and other objects that can be used in other parts of the project. By breaking down code into smaller, reusable modules, developers can avoid duplicating code and make it easier to maintain and update.

Packages, on the other hand, are directories that contain multiple modules. They are used to group related functionality together and provide a way of organizing larger projects. A package can contain sub-packages, which can in turn contain further sub-packages or modules. This allows for a hierarchical organization of code that...
