There are some additional super useful functionally worth mentioning: 1) In the toml file, there are special characters that define/limit how to update dependencies versions (^, ~); 2) the lock file “locks” the exact versions for dependencies and transient ones. This ensures reproducibility and is a game changes for production ready code. it is possible to test updating packages and only committing the new .lock file if everything works. 3) poetry has a cli tool to auto bump the package version (major, minor, patch) which makes it even easier when managing a package 4) for some compatibility cases, it is also possible to export the dependencies into a requirements.txt file (for example, when using serverless framework to deploy an AWS Lambda function using the pip-requirements plugin)

Poetry is a 10/10 project tool IMO. Im glad I was able to convince my team to move over to it.

I don't think it can be underestimated what a "rabbit hole of pain 🙂" this topic can be for the python programmer who is moving beyond the basics (I know from personal experience lol). Especially compared to `cargo` in Rust. Poetry has simplified my Python development, and this is an excellent video in getting started with it. Thanks for all your great videos!

This has to be one of the best and most concise tutorials I've watched lately. I've been using virtualenvs and venvs with pipfiles for years, but this looks like the next logical step. Thanks!

This is a great video to understand the use of poetry. After this video, I find the official Poetry documentation making a lot of sense. Thank you!!

I'm using pyenv to manage python versions, and then having poetry creating creating a virtual env inside the project. Really glad with this setup.

I've actually been using conda for this, even for non-Python projects, and it worked well for me so far

Finally sounds like theres a decent python project package manager. Can’t wait to use it

This was really well explained.

So glad this video finally came out!!

Thanks for this!! I started playing with Poetry a little while ago and needed this video!

At work we started using poetry, it helped us a lot to deploy and also manage de dependencies.

you're a champ Arjan

Thanks Arjan, was waiting a long time for this video. Finally Poetry gets explained in a good and clear way!

Thank you son much exactly when I tart learning poetry😊 excellent tips to delete old env and reinstall them evently to limite size of project

Poetry is life! Seriously it's a great tool, at word we use it all the time and for my personal projets I would use it without an hesitation too!

Good video! I've been using poetry for some time now, and recently ran into the case where you have a poetry project that uses a python version that needs to be updated, which means you have to manage multiple python version in your system and need to tell poetry to go from one version to another. That would be a really good topic for another video as I see a lot of confusing information online about pyenv and poetry working together

Thanks a lot for this video. Loved it :)

Love the videos & quality work you put into them. Could you at some point do some examples, such as: wave function collapse, etc ...?
