Thanks for covering the role of __init__.py in the import of a module. Because a lot of video tutorials skip this information.

This is a great start on this topic. There arent actually a lot of youtube videos about this topic, and its hard to find information. Would appreciate a follow up that went more into detail, if you can. For instance: what exactly happens when you import things in the __init__.py file. What sort of start up logic do you need to do. What is the appropriate use of this file etc....

you should mention the difference between having _init_.py and not having one in your module directory

that one class I ignored, it was this one in 2021. i got it now 😂 thanks for this!

Thanks for this basic tutorial about imports, could it be possible to make a video about imports between modules in the same package ? cause this is always a pain in the a** to know how to do these correctly and everyone seems to use different tricks when searching for solutions on the net. That would be a really helpful video

Good job! Pycharm was a nice touch since that’s the environment that many use.

The __all__ dunder method is something i didnt know yet. Neat

It would have been interesting to see the behavior of __init__.py when importing the same package from multiple different modules within your project. If I'm not mistaken, the __init__.py will be called only once (the first time any import statement is used).

I use "__init__.py" also for importing all the libraries that I will import in the submodules. And then, in the submodules, I use "from . import <something>". I don't know if it's useful, I wanted to have organized imports.. Does it make sense?

[GregMeece]

FYI, from what I can tell, VS Code doesn't change the directory icon when you declare it to be a module (by adding dunder init . py).

Thank you indeed... Extremely clear, concise... Thank you ...
