The assignment operator - or walrus operator as we all know it - is a feature that's been in Python for a while now (since 3.8), yet it's still somewhat controversial and many people have unfounded hate for it.

In this article I will try to convince you that the walrus operator really is a good addition to the language and that if you use it properly, then it can help you make your code more concise and readable.

In some of my recent streaming sessions (some of which you can see on my YouTube chanel), I spent some time playing around with Dijkstra’s algorithm. I wrote my own version of it in Haskell, tried to generalize it to work in different settings, and then used it in some examples. So for the next couple weeks I’ll be writing about those results. Today I’ll start though with a quick overview of a basic Haskell approach to the problem.

Cram is a single-file Python 3.6+ zip app, designed to be something you can just check in with your dotfiles and run anywhere using a system python interpreter. Cram provides a package abstraction like Stow with the addition of packages which can exec. Most importantly, Cram hews to immutable infrastructure principles with an execution log, dry-run/diff capabilities and supports automatic removal of installed resources.
