Module PackageWe can talk about functionally similar functions in a folder, forming a module package.However, the folder must contain a __init__.py file that reminds Python that the folder is a module package. __init__.py can be an empty file.For example: In the folder Dir, there are two function files add.py and sub.py, of course there is a __init__.py, then we can use the following methods to introduce:Import Dir.addImport Dir.subFinally, put the code on.__init__.py:# is emptytest.py:From Dir
