A succinct tutorial on how to use the __init__.py file to import directories as python libraries.
Welcome to my series for Learning Python, where I will be teaching fundamental concepts in the Python programming language.
These videos will focus on one aspect of Python at a time, but your understanding of the material will be greatly improved through usage. I recommend applying the concepts described here in your own project, or viewing the Developer Diary series where I use these tools on bigger projects.

Hello everyone! Another user was having a problem that I want to share with you guys. When you import a package to python, the interpreter searches several paths to find your library - one of which being the working directory. If, however, one of those other paths has a library with the same name, that one will take precedence! If you create a library called Matplotlib, python will still import the original instead of yours!

Finally a short and to the point tutorial that actually tells me what the frick a __init__.py is and how to use it, thank you!

@ajayjoseph4498 3 года назад

I came here to learn __init__, but the way you have demonstrated is absolutely amazing; now I understand what from, import, and __init__.py do. Brilliant!.

@eom-dev 3 года назад

Thank you! I appreciate it!

@PatrickSteil Год назад

Same! Good job

@MarkSmith-vo1vn 26 дней назад

Slight correction. I haven’t finished watching it yet. But if you do import resources.object_ones. You can do object_ones.Ones(). That’s it. It’s more to type, which is why the from is used. But you will often see packages like pandas like this. import pandas as pd. Then we do pd.DataFrame() blah blah.

You're a gem! Such a great teacher! If everyone taught like this anyone could learn Python in days!

@mihailb0r0koko89 2 года назад

Jeeez I always used init files without typing in anything. 2 years passed here I am finding out this blessing of information. This will clean up a lot of mess in my projects. Huge thanks!!!!!

@derekknowlton2384 2 года назад

Thanks for that clear description. This make reusing code so much easier. I have been trying to figure this out for two weeks.

@mrc1500 Год назад

Thanks, Eric. This short video was just what I was looking for. I'm a Python newcomer and packages have been difficult to grok until now.

@davidnobles162 Год назад

Thank you! The first two minutes explained my confusion about why some of my code would work without errors when other code wouldn't. Definitely helped me. Thanks!!!

@poncelas91 Год назад

Very good explanation. I was wondering why a lot of projects had hundreds of lines of code added to their __init__ file and this has helped a lot. Thanks mate!

@kcvinu Год назад

Is it possible to write conditional import statements in __init__.py ? i mean, If I have a package with 50 files and I want to use 10 among them in one case and in another case, I want to use 30 among them.

@TomWelch-l5q 19 часов назад

Thank you so much for this video! However, I was wondering if we could simply use "from resources import *" to avoid specifying which object we're trying to import? Thanks for your help!

@airatvaliullin8420 Год назад

I think you can also write something like __add__ = ["object_one", "object_two"] inside of this __init__.py file.

@kalekber 3 года назад

That was straight up to the point. Can you make more vids on tricky parts of python? Some concepts might be challenging to wrap your head around, especially from someone coming from other languages.

@eom-dev 3 года назад

Thank you, I try to make videos like these as the topic comes up in my daily workflow. If you point something out to me, though, I'd be happy to make a video on it.

@kalekber 3 года назад

@@eom-dev I have some topics in mind. How to structure a python code since, I have noticed that untyped languages are not ideal for big projects. And another topic that would have been sweet is software development architecture styles. Those two topics always come up together.

@liamhuang2687 2 года назад

Hi Eric, what if the modules you want to import are from a different directory (non-parental relationship)?

@theeox Год назад

You would either create another _init__.py or move the files in such a way that you can call them. Think if the libraries as if they are in a file structure. As long as the Python_path has the folders in the parent path then you can call them. This is about not having to recall functions over and over again and being able to utilize one file to establish everything in a collective state.,
