How is a package with an empty init.py file structured to give access to its modules when you import it? There's no particular structure necessary. If you have my_module containing __init__.py and my_submodule.py, then you can import import my_module.my_submodule with no additional work at all. Answer from Deleted User on reddit.com

r/learnpython on Reddit: Can __init__.py actually be empty?

April 4, 2020 -

Many tutorials seem to imply that the typical __init__.py file in a package is empty. But this never works for me. Typically, I start a project by writing a series of .py modules in a directory. When I decide my project could be useful in other projects I'm working on, I try to turn it into a package by adding an empty __init__.py file. But when I try to import that package, I don't have access to any of the modules I wrote unless I import them in the __init__.py file.

Is this normal? How is a package with an empty __init__.py file structured to give access to its modules when you import it?

Assuming your package looks like this: package |-- __init__.py |-- subpackage.py An empty __init__.py won't let you do this: import package instance = package.subpackage.Class() But it will let you do this: import package.subpackage instance = package.subpackage.Class()

class Point:
    def __init__(self):
        pass

As @jonrsharpe said in comments, you can use the default arguments.

class Point:
    def __init__(self, x=0, y=0, z=0):
        self.x = x
        self.y = y
        self.z = z

Now you can call Point()

python - How is an empty __init__.py file correct? - Stack Overflow

Empty files are perfectly fine:

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.

Depending on what you plan to do it's a good place to import public stuff from the modules in your package so people can simply use from yourpackage import whatever instead of having to use from yourpackage.somemodule import whatever.

Answer (1 of 5): It means that the __init__ method is inherited If you actually specified a parent class, then the __init__ of this parent class will be called If you didn't, it will use the object __init__ method, which doesn't do anything significant for you This behavior is the same as non-...

September 6, 2023 - In the webpage: https://packaging.python.org/en/latest/tutorials/packaging-projects/ was stated the following: "init.py is required to import the directory as a package, and should be empty." It did not work for me. Instead, when I wrote my methods in the init file as before then it worked.

I've been looking into some projects for some opensource software i use and noticed a few of them have empty __init__.py files (for example https://github.com/netbox-community/netbox/blob/develop/netbox/core/__init__.py)

From the official docs : The __init__.py files are required to make Python treat directories containing the file as packages. This prevents directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later. Users of the package can import individual modules from the package, for example: import sound.effects.echo This loads the submodule sound.effects.echo. It must be referenced with its full name. sound.effects.echo.echofilter(input, output, delay=0.7, atten=4) An alternative way of importing the submodule is: from sound.effects import echo This also loads the submodule echo, and makes it available without its package prefix, so it can be used as follows: echo.echofilter(input, output, delay=0.7, atten=4)

python - What is __init__.py for? - Stack Overflow

It used to be a required part of a package (old, pre-3.3 "regular package", not newer 3.3+ "namespace package").

Here's the documentation.

Python defines two types of packages, regular packages and namespace packages. Regular packages are traditional packages as they existed in Python 3.2 and earlier. A regular package is typically implemented as a directory containing an __init__.py file. When a regular package is imported, this __init__.py file is implicitly executed, and the objects it defines are bound to names in the package’s namespace. The __init__.py file can contain the same Python code that any other module can contain, and Python will add some additional attributes to the module when it is imported.

But just click the link, it contains an example, more information, and an explanation of namespace packages, the kind of packages without __init__.py.

Files named __init__.py are used to mark directories on disk as Python package directories. If you have the files

mydir/spam/__init__.py
mydir/spam/module.py

and mydir is on your path, you can import the code in module.py as

import spam.module

or

from spam import module

If you remove the __init__.py file, Python will no longer look for submodules inside that directory, so attempts to import the module will fail.

The __init__.py file is usually empty, but can be used to export selected portions of the package under more convenient name, hold convenience functions, etc. Given the example above, the contents of the init module can be accessed as

import spam
