Last year I posted a similar Ask HN; it got 11 comments: https://news.ycombinator.com/item?id=38505531. I asked, "What lesser-known Python libraries do you wish people knew about?" The suggestions there are worth looking up. Don't miss DiskCache (https://github.com/grantjenks/python-diskcache).
I really like xmltodict (https://github.com/martinblech/xmltodict). Despite the name, it works in both directions. It is the most ergonomic library I have used for creating XML. It has external type stubs: https://pypi.org/project/types-xmltodict/.
Since you have recently discovered Rich, you may want rich-argparse (https://github.com/hamdanal/rich-argparse). It colorizes argparse CLIs with little effort from the user.
DeepDiff (https://github.com/seperman/deepdiff) has helped me with testing. I needed to compare two nested data structures but ignore any differences in floats (timestamps). DeepDiff let me do it:
diff = DeepDiff(
run_session(config), run_session(config, force=True), exclude_types=(float,)
)
assert not diff
pzp (https://github.com/andreax79/pzp) is like fzf in pure Python to use in your programs.
Keep in mind it is currently version 0.0.x.
I have found bugs, but I think it is just cool that it exists.by Crier1002 on 7/31/2024, 9:59:02 AM
I use https://github.com/litl/backoff for configurable backoff + retry
context: OpenAI API used to be super flaky back in the early days, i needed to retry my requests quite frequently and i found this

For audio analysis:
Audio track seperation:
https://github.com/adefossez/demucs
demucs works pretty well.

Defopt generates cli from function interface: https://defopt.readthedocs.io/en/stable/features.html
The alternative is either you maintain two interfaces with boilerplate, or write a cli only if that’s the first priority.
Similar solutions exist, like fire. But fire’s cli is like an afterthought, in the sense it gives people a way to run things in command line where they already know how to run it from Python.

This has been an absolute game changer: https://github.com/pytries/marisa-trie (succinct trie with fast lookup and minimal RAM) Use case and more details in the wonderful book by Ian and Micha: High Performance Python

pg8000 [1] is a Postgres library implemented in pure Python. I've spent enough time trying to get psycopg installed on MacOS and Docker that I appreciate just being able to pip install it at any time.

Hey everyone! I'm always on the lookout for new and interesting Python libraries that might not be well-known but are incredibly useful. Recently, I stumbled upon Rich for beautiful console output and Pydantic for data validation, which have been game-changers for my projects. What are some of the lesser-known libraries you've discovered that you think more people should know about? Share your favorites and how you use them!
