*Here we can see that first we are using def function to call 'two' and then in another file we can call the function by name ('two').
More about module:-
In programming, a module is a self-contained unit of code that contains functions, classes, and variables related to a specific purpose. Modules are used to organize code, make it more modular, and promote reusability. They provide a way to break down a large program into smaller, manageable components, making it easier to maintain and understand.
In most programming languages, modules are implemented using files. Each module typically corresponds to a single file that contains the code related to a particular functionality or feature of the program. The module file can be imported and used in other parts of the program to access its functions, classes, and variables.
Advantages of using modules in programming:
1. Encapsulation: Modules encapsulate related code, making it easier to manage and reducing the chances of code conflicts or naming collisions.
2. Reusability: Modules promote code reusability. You can import a module into different parts of a program or in other projects, avoiding duplication of code.
3. Readability: By breaking the program into smaller modules, the code becomes more organized and easier to read and understand.
4. Maintainability: Modular code is easier to maintain as changes and updates can be made to individual modules without affecting the entire program.
5. Collaboration: Modules enable teams of developers to work on different parts of the program independently, facilitating collaboration and parallel development.
In many programming languages, like Python, JavaScript, and Java, modules are a fundamental part of the language, and they are widely used to build complex and scalable applications. By using modules effectively, programmers can write cleaner, more maintainable, and efficient code.
