Graphics.primitive package into the current namespace. However, because of the different file name rules between different platforms (such as case sensitive issues), Python does not correctly determine which modules are to be imported. This statement only runs sequentially The __init__.py file under the Graphics and Primitive folders. To solve this problem, you should define a list of name all in the __init__.py below the primitive folder, for exampl

Referencing in Python is a very simple thing, and there are three concepts that you need to know about packages, modules, and classes. Class This is needless to say.The module corresponds to a. py file, and then Module_name is the file. The file name after the. py file can be directly defined in the py files, with variables, functions, and classes.Then we can think of the package as a folder containing __in

1. Module Import methodCommon scenarios:A module is a file containing python definitions and declarations, and the filename is the suffix of the module name plus the. Py , and the import module allows for the reuse of the function.Import loaded modules are divided into four general categories:1 code written using python (. py file)2 c or C + + extensions that have been compiled as shared libraries or DLLs3
