Python Libraries

Look, there's a staggeringly gigantic collection of Python libraries out there. This isn't that. This isn't even 1% of that. This isn't even 0.01% of that. What this is is just a list of libraries that I personally use regularly and find to be good. Hopefully that might be a lead for people looking for something to scratch an itch.

HTTP

HTTPX

An alternative to the ever-popular requests. I switched a while back because it had better type annotations, but I feel like there was another reason I switched, but I can't for the life of me remember what it is.

Barcodes and Labels

pylibdmtx

From the Natural History Museum in the UK, this library lets you both create a parse Data Matrix barcodes. You can see a use in this project. There's another library, pystritch, which is used by blabel below, but it seems to be somewhat abandoned. It works, but...

python-barcode

Great library that does nearly all the 1D barcode formats: Code 39, Code 128, EAN-13, EAN-8, JAN, ISBN-13, ISBN-10, ISSN, UPC-A, EAN14, and GS1-128.

qrcode

Library for creating QR codes.

Blabel

This library from the Edinburgh Genome Foundry provides a simple interface to use HTML+CSS+Python to define labels, including lots of barcode symbology. While things like the Brother P-Touch editor are great for small sets of labels, this is the thing you want if you need to generate labels in the hundreds or programmatically.
