What does '__init__.py' do in Python?

If you've read a fair amount of Python code, then you've probably seen this "__init__.py" file pop up quite a few times. It's especially common in larger Python projects. I'm going to breakdown exactly what this file is, when you should use it, and exactly how it works.

I'm learning Fast Api and I kept using these __init__.py but I never knew why they were used. Thanks Tim. It was such a great tutorial.

The internet gives me access to so much information, it's like having a genius classmate whose brain I can pick for free. Thanks, Tim, you're a lifesaver!

I’m excited to see more beginner friendly videos like these for fast api, Django, etc. Great content, Tim!

[alexandrekononov]

Thank you, great video. Working with packages is such an important and yet slightly overlooked topic!

one of the most clear and concise video

[selomamuzu]

As much as i enjoyed the advice videos. These type of videos are way better. Please do more like this

[oqba]

You explained everything with clarity and actual meanings, you got 10/10

[ScottyMcCraigles]

Videos like this are super handy. Can you make a video series on topics like this, please!?

[ashutoshmishra]

Please upload this type of videos. These are effective rather than the advice videos. That's my feedback idk about others.

AI tools will create millions of beginner and intermediate coders that can get by. But listening to guys like Tim will actually make you competent at a deeper level that understands the whys the what’s. Which will speed up your progress exponentially.

Thanks for this video! Needed this as I never understood the use of __init__.py and how the relative imports worked (recently found out while debugging code at work).

[Avuvos]

Very much needed, great stuff, thanks!

[patrickmateus-iqbi]

I was still using the init file this whole time.😂.... I learned something today. Thank you Tim

[markrich]

Finally understand __init__.py! Thanks, Tim!

Thank you Tim. I'm learning Python right now, and coming from a CommonJS (NodeJS) background, I'm kinda lost as to how the import system in Python works.
This video helped me clarify some things.
