Modules also have Python built-in modules, and third-party modules, different modules can have the same function name and variable name, the module can be organized into the package, different package can have the same module name. Note that there must be a __init__.py file under any package, it can play the role of the compiler to identify the package, that is, it is the package!

As in the picture, you can also organize multi-level catalogs, in the MyCompany package, there are several modules in the web package = =, the figure has two __init__.py files, a corresponding Web package, a corresponding MyCompany package. Standard file module for Python modules.
