Module vs Library (in java?)
Module is a file which contains various Python functions and global variables. It is simply just .py extension file which has python executable code.
Package is a collection of modules. It must contain an init.py file as a flag so that the python interpreter processes it as such. The init.py could be an empty file without causing issues.
Library is a collection of packages.
Framework is a collection of libraries. This is the architecture of the program.
Application is an application. Yah, Iโm sure about this one.
