How to Use Poetry in Python to avoid Dependency Hell

Today, let's discuss Python dependency, virtual environments and the use of Poetry, an all-in-one tool for virtual environments, dependency management, packaging, and distribution in Python projects.

I'll explain how Poetry helps manage dependencies, set up virtual environments, and package projects for distribution.

I'll also mention the limitations of Poetry when dealing with non-Python dependencies or C-based dependencies, recommending the use of containers in such cases.

The explanation of Poetry and comparing it with other virtual environments has been like none I have seen before. Its a wonderful explanation. The only thing I would have liked to see in addition to what you showed was an EXAMPLE where there is a dependency conflict in some modules and how introducing poetry will resolve the issue.

this video helped me with 80% of getting there, now I need to look for where to add the hello world code and how to run it

as to future potential topics,
python typing looks not very clear when I write class methods for non-builtin classes. also wondering since which python3.* does this typing has really performance improvements (or "dev acceleration" as IDE use them)

Nice. I like the choice of toml - aligns with Rust - my other language.

At 8:25 what he is actually tell about the git commit ???
I didn't get that, can any one helps me to understand that ??

[kristiannn]

this is one of the best videos on youtube about dependency management in python

[hazard_]

Great video. Can you please do one on Pants build system as well?

[NamasenITN]

Can I install poetry with poetry? Or will it cause an anomaly in the space time continuum?

[cerkal]

Explanation was nice. But I think you have missed main part of video that is how to avoid dependency hell. Like when installing two packages which use different versions of same depended package is still resulting in error. Which you explained in the earlier section of the video but didn't actually explain if it could be solved or not using peotry.

This happens to me, it was shit I spend whole day trying to work it out I notice the problem is different dependency on different python version ugh

1. What if I don't want to publish my package on pypi but use it on my own local machine as a single executable? For example on Windows machine as an .exe file, how can I build this file?
2. And in this video it is not clear, how poetry breaks the diamond that you show us at the beginning of your video. What if we need two different version of the same package, for two libraries we need in our project, how poetry breaks the diamond and put two different versions of the same library in venv?

[BryanChance]

I don't know which is worse python or nodejs

[JevKuznetsov]

To go one step further - devcontainers are an even better solution. Build once - reproduce on any system.

Python is supposed to be so clever terse and elegant. If it was an apartment, it would be as spotless as patrick bateman's, but they have such a pile of garbage outside you need a Shai-Hulud to get to the door. Just a little poetry there.

I LOVE this video but please make the Internet a better place and stop referring to directories as "folders". Thumbs up! Also, the term "open source" is totally lame. The proper term is "Free Software".
