for some reason this showed up in my feed, good stuff my guy. keep it up

Important detail that mixes people up a lot (and results in a lot of repeat questions on StackOverflow) --- If the scripts in your package rely on elements of other files in the same package via imports, they MUST use Relative imports.
However, if you also have a main script or test script within your package that you want to run directly (as opposed to having an external main.py import your package), then that script within the package must use Absolute imports. Python determines whether or not it should be using relative or absolute imports based on whether or not the script it is processing is in a package, and the top-level script (the one invoked with 'python my_script.py') is never considered to be in a package while it is interpreted.
If you insist on having scripts in your package that you want to run directly, put the intra-package imports in a try/except block, where you first try the relative import, catch an ImportError, and then try absolute imports.

I just found your channel from the Youtube recommendations. The 2 minute videos are a great idea!

I do a similar import without __init__.py file and it works fine. What is an example of import which wouldn't work without that empty file?

[有賀_竜樹]

So it's basically Python's way of declaring namespaces with optional super constructor functionality. That's what I understood.

Great vid btw! :)

Somehow saw your vid by youtube recommended algorithm! I think I like the concept of explaining something really important and widely used in a short amount of time like 2-minutes! It was really good, maybe if more complex topics need to be explained then I think you dont need to keep a 2-min constraint. It can be extended up to 10min but not more than 10min. Maybe just keep it compact like this. Anyways great work !

__init__.py currently can be used to expose class or function. Taking the example in the video, if you want to expose the function "say_hello" in "greeting.py" to "my_package" level (i.e. in other arbitrary script, you want to "import say_hello from my_package"), you can write the line: "from .greeting import say_hello" in "__init__.py" to achieve this goal.

explanation is clear concise to the point.. no redundancy. love it.

[Fizzulko]

Great video, keep making new ones. The way you explain things in 2 minutes is amazing ! Great work !

[arvindh]

Also can help in abstraction and encapsulation(__all__) too

[vasutke]

High clarity, Excellent Presentation and ultimate communication very interesting video. Thanks and Regards.

[dheeraj]

I can't thank you enough for this. This is the best explanation ever. Thank you very much

[MissingTricks]

Absolutely hidden information, I couldn’t found out this in udemy courses. Thank you🎉

[epokal]

This needs so much more engagement, also i might comment another just for engagement purposes

[moralfuxery]

Omg what an amazing video to come across while in my first weeks of using python. 👍👍👍

[Kothwalashivakumar]

Greatly explained in the most simplistic way possible. Thanks

[markmilan]

Great startups! Keep on making more videos.

[baderhelsing]

Almost a day of searching why I'm getting "No module error" and I'm just missing init file for the imports folder, Udemy and coursera is missing these in their python selenium courses. Great video brother, you save my ass.

Thank you so much! That was so easy to understand ✨
