In this article, we saw how to import classes within the same directory as well as a different directory. The files A.py and B.py contain two classes, Aclass and Bclass, which we will import to the main.py class. Import path hooks are called as part of sys.path (or package.__path__) processing, at the point where their associated path item is encountered. For the files in sub-directories or sub-sub-directories, we have to add another .subdirname as shown below. In the __init__.pyof the directory you want to include recursively: python importpkgutil __path__ =pkgutil.extend_path(__path__,__name__) forimporter,modname,ispkg inpkgutil.walk_packages(path=__path__,prefix=__name__+'. The __init__.py shown there would have also allowed the usepackage.py script to have been written this way (package maps to subdir in your question, and Class1 to myclass01, etc): Oops, sorry, the code in my other answer doesn't quite do what you want it only automatically imports the names of any package submodules. So any of its subdirectories that happen to have an __init__.py become python packages.

To make it also import the named attributes from each submodule requires a few more lines of code. if not using a subdirectory: Since you are using Python 3, which disallows these relative imports (it can lead to confusion between modules of the same name in different packages). Import class from a file in a different directory Packages The most Pythonic way to import classes from other directories is by using packages. . For the files in the sub-directory, we have to follow the following notation. So package relative imports no longer work. Note: Check out the downloadable materials for some tests that you can run on your machine. __import__(modname) More Context For each level of directory, you need to add to the import path. You define a setup.py and, well, there are multiple options on how to set things up there. The tests will compare the time it takes to return a list of all the items in a directory using methods from the pathlib module, the os module, and even the future Python 3.12 version of pathlib.That new version includes the well-known walk() function, which you won't cover in this tutorial. It is a built-in function of the sys module that can be used with a path variable to add a specific path for interpreters to search. You might need to use python -m to run the script from the parent dir and use absolute imports. Import path hooks are registered by adding new callables to sys.path_hooks as described below. The import statement imports the Aclass and the Bclass in main.py. The programmer has to utilize the list dir and list all the py files. Here's a modified version of the package's __init__.py file (which also works in Python 3.4.1): Alternatively you can put the above into a separate .py module file of its own in the package directorysuch as _import_package_files.pyand use it from the package's __init__.py like this: Whatever you name the file, it should be something that starts with an _ underscore character so it doesn't try to import itself recursively. Inside the directory, there is an __init__.py file. Python Import Class From Another File Using sys.path.insert () Method. In the folder productname you wanna specify what imports you can run from a module on the same level: Now you should be able to import your file into your main.py with: Python follows an execution model very close to regular programs on your computer. So if the directory was named "classes", then you'd do this: Same as previous, but prefix the module name with a . Add the parent directory to the sys.path using the append () method.
