- The last part of the module import path is the module name. This also becomes the Django app name. Apps names have to be unique. Hence, there is no scope for two different modules with same name but different load path to exist in the project. - Most uses of list of loaded modules are dealing with app names instead of full module load path. This is due to the fact that Django deals with app names and not module paths. - It is also somewhat clumsy to access a loaded module as we are re-importing every time to get access module. - Simplify all of the above by using app names are module identifiers and maintaing an ordered dictionary of app names to loadded modules. - Remove unused imports. - Minor styling fixes.
