9. Modules in Python and Working on __name__ || SpecialVariable (Basic)

Modules in Python are files containing Python code that can be reused in other Python programs. Modules are an essential part of Python's modular programming approach, allowing you to organize code into separate files and reuse code across different projects. Importing modules is the process of bringing code from one module into another module, enabling you to access the functions, classes, and variables defined in the imported module
The special variable _name_ is a built-in variable in Python that is used to determine whether a Python script is being run as the main program or if it is being imported as a module into another script.
Modules and Special Variable (__name__) implementation is also explained with the help of a working example
