The __init__.py file can be empty, or it can have the code needed to initialize the package and a list of the modules required to be imported with the package; this list is represented by the __all__ variable. set the __all__ variable, described later. module. The parameters have the same meaning as they do We can access a module, variables, files from a subdirectory using two different functions.
