In this video, we're gonna be discussing about the use case of __init__.py in Python or simply init.py in Python. We'll talk about its relevance prior to Python version 3.3 and earlier and its use case from Python 3.3+. We'll talk about the two important functions of __init__.py in Python Packages which are the reason why its still being used. Stay with us...

@abdulazizalmniey 3 года назад

Just amazing, I was looking for this, I had to import every file in the folder, but now I can just import the folder and the __init__.py will import them all for me.

@abdulazizalmniey 3 года назад

Unfortunately that caused a "circular dependencies", so I guess no luck for me with this.

@yarontaub 4 года назад

Thanks for the explanations. I hope you don't mind some constructive criticism - you say "you know" A LOT. Dozens of times. It makes it very hard to follow along. One way to avoid it, is writing down what your going to say. There are other methods as well. But you should really kick this habit. Subscribed :)

@CodeBand 4 года назад

Sorry about that and that was an issue i faced a lot...and I believe in the recent videos, the so called "you know" comes rarely...and thanks for subscribing...will keep on posting good contents... :)

@daniellive590 4 года назад

I got a question for my understanding, from your first use case, you wrote from functions import add. That is redundant right? Since in the __init__.py, we have from.arithmetic import * (all) ?

@CodeBand 4 года назад

Great question👍🏻 The thing is that __init__.py is only run once we invoke/import the package we wanna use, so here, if we omit "from functions import add", it would not invoke the __init__.py file and hence we could not use the add() function. But, if I say like just the "import functions", it will trigger __init__.py, but the line inside __init__.py is executed there itself, and not in the current main.py, and so, we would not be able to access add() function. To make it clear, if we break "from functions import add", then, "from functions" will trigger/invoke __init__.py which will execute from .arithmetic import * there itself, so that the next part, "import add" is accessible. Hope this helps😊

Hi, I need to know how to use init and import a file from one folder to another folder where both the folders are in the main folder.

@CodeBand 4 года назад

@clueless_nidget 4 года назад

@@CodeBand I am not getting through Google. Example: I am having a folder named Main. Inside this folder I have 2 folders a and b. Inside both folders I have 2 files each. a containing init and test1, b containing init and test 2. I need to import test 1 in test 2. I tried those from ..a.test1 import function but while running there is an error. Could you help me solve this?

02:54 Import in main.py

@krishnajunk 4 года назад

Good. But you missed siginificnce of "functions->Sub_pkg->Arithmaetic" and directly used "functions-->Arithmaetic". Looks you missed to explain. Also What is "Functionf" directory here ? Is it root .. I think yes as you are using a pyhton IDE app? If I use git-repo, and I am in some subdirectory calling function ... But Overall it is good.

@CodeBand 4 года назад

Actually, I deliberately missed "functions->sub_pkg->new_module.py" as I believe, I mentioned in the video that it is a challenge for you to work around. Actually, the "packages" directory is the project directory which has main.py(root python file) and a package named "functions". Hope I answered the question, and anyway thank you and keep supporting.. :)
