In the vast universe of programming , modules are a fundamental tool that facilitates the development of efficient and maintainable software. These modular components allow programmers to divide large systems into more manageable and reusable parts, simplifying the development process and improving code readability .

Definition of a Module.
In simple terms, a module is a file or logical unit that contains code that is related to each other. This code can consist of functions, variables, classes, or other programming structures. The main idea behind modules is to break down a program into smaller, specialized parts, making it easier to understand and maintain.

Advantages of Using Modules:
Code Organization: Modules allow you to organize your code in a more orderly fashion. Each module can address a specific functionality, making it easier to identify and understand each part of the program.
Code Reuse: By dividing code into modules, it is easier to reuse functions or classes in different parts of the program or in other projects. This promotes efficiency and reduces code duplication.
Facilitates Maintenance: When an update or correction is made to a specific functionality, only the corresponding module needs to be modified. This minimizes the risk of introducing errors into other parts of the program.
Collaboration: In large projects, different developers can work on specific modules simultaneously, making collaboration easier. Well-defined modules allow teams to work independently in their assigned areas.
Module Types:
Built-in Modules: Many programming languages ​​offer built-in modules that provide basic functionality. For example, in Python, there are modules such as mathfor mathematical operations and osfor operating system operations.
Custom Modules: Developers can create their own modules to address specific needs of their projects. These custom modules contain functions and classes designed for a particular purpose.
