The limitations that come from the language syntax and language nature (dynamic, functional, object oriented, and the like) can differ, as can the reasons behind their existence To know more about design patterns basics, refer – Introduction to Design Patterns. The only difference here is that your application code is now all held in the helloworld subdirectory—this directory is named after your package—and that we’ve added a file called __init__.py.Let’s introduce these new files: helloworld/__init__.py: This file has many functions, but for our purposes it tells the Python interpreter that this directory is a package directory.
