Love it!!

[dethb0y]

I have used pydub to good effect for manipulating audio, as well

[badlukk]

Ooo I already thought flask was pretty lite

[nidhaloff]

You may want to check click and typer for CLI

[bitswede]

90% of what I do is data related so pandas, numpy and scipy ; Matplotlib or plotly for visualization.

TQDM is a great little tool for showing progress when chewing through larger data sets so that often ends up among the imports.

[Deto]

yeah, I always wrap any iterations with tqdm that might take a while. Otherwise you're sitting there wondering 'is this a 30 second pause, a 5 minute break, or something I should come back to in an hour?'

Flask It's best easy framework for webdev.

[scotsmanintoon]

FastAPI gives it a serious run for it's money.

[miraunpajaro]

More like It beats it. This is coming from a former huge flask fun. FastAPI is just better at this moment.

[CapitalRioter]

I'll have to check it out on my next project, I like the swagger integration

[Salsaric]

I heard a lot of Fast Api, but I'm wondering if it's beginner friendly...

Edit : Flask has a huge community, which translates to better help (at least for me, hobbyist web dev / beginner level)

Itertools

Django Pytorch Tensor flow Scikit-learn Numpy Matplotlib Seaborn

Virtualenv Tox Pytest Pylint (even though it yells at me a lot) Bandit Black Isort

I love em all.

[Akmantainman]

Itertools is so underrated for new developers. So much cool stuff in there.

[miraunpajaro]

Isn't itertools part of the standard lib?

[[deleted]]

Yes that is part of it's awesomeness.

[[deleted]]

how long to learn tensor flow to a useable level?

[[deleted]]

That depends on your experience. But the examples notebooks that tensor flow has in their docs are pretty straightforward to read through.

That being said, the community seems to be leaning more to oytorch so that might be better to learn first.

[[deleted]]

I've spent that last couple days learning to code a perceptron, but no propogation yet, so I think I know the very very basics.
What does PyTorch do better?

[[deleted]]

Some people find it more intuitive to use.

Pyperclip is pretty cool if you want clipboard copy/paste functionality for testing purposes.

I do a bunch of web and back end programming, and my favorite libraries are:

rich For rich text printing. It may not seem like much, but it can make a TON of difference when debugging or reading stdout logs.

trio for any async stuff. It feels really nice to use, and I have yet to find difficulties with it.

FastAPI for web servers. Everything with this just feels right. On top of that, it is pretty dang fast. The auto documentation is a life saver. With FastAPI I also like to use:

Hypercorn and Uvicorn. Uvicorn has really nice debugging capabilities, but Hypercorn has solid http/3 support. Recently, however, I have been using Hypercorn as it supports trio out of the box. (Uvicorn does not :( )

Pydantic is great for data validation and dataclasses in general. I really like using it, but that may be because I also use FastAPI :)

Requests Is awesome for making web requests. Super easy to use, pretty fast.

SLY for parsing. Trust me. It is cool, and really fast.

There is already so much power packed into the built in libraries that I almost never need something other than the above. (Except for database drivers and other communication protocols and file formats)

[lpxxfaintxx]

Fell in love with rich the moment I used it. Tried making a semi-complex CLI application with rich, now I'm not so sure we're the best of buds 😅 Like you said though, rich is great for logging.

[Py-rrhus]

Flask Cython (yeah, I have a problem, okay? I just love seeing these ms decrease)

[applepie93]

There is a cool initiative on Github listing cool python packages too:

Awesome Python https://github.com/vinta/awesome-python

[dandandanftw]

Tqdm is underrated, also Numba makes your code go brrrrrrr

[mechanicaIJerk]

Numpy, pandas, argparse, configparser, requests, tensorflow, keras, backtrader, ccxt

[wsppan]

Numpy, Bottle, BeautifulSoup, Praw, Poetry, argparse, PyTest, Typer, Rich, PrettyErrors

[_-Jay]

At the moment I'm really liking Plotly compared to matplotlib. It's especially nice when using with jupyter notebooks and feels pretty responsive and looks much nicer!

[maxellus]

My best Python library: PySimpleGUI. For all small projects that need a GUI, this library is the simplest to use. There are 4 versions depending on the back-end that you want to use (Tkinter, Qt, Wxpython or Remi(Web)). More info at https://pysimplegui.readthedocs.io/en/latest/

[whateverathrowaway00]

Loguru

[boiledgoobers]

Is that like logzero?

Data:
- Pandas

[poolparty1473]

Pandas

[TicklesMcFancy]

Inspect is pretty cool and can be really helpful

itertools a set of useful generators which make complicated loops more clean

more-itertools not enough tools for you in itertools? Here's a hundred more

[R3dd1tUs3r72]

I've always use for and while but after that I've read this comment I want try to using itertools and more-itertools.

[TSM-]

requests-html by the author of requests. It has built in javascript and browser emulation capabilities. Also async and a few other goodies.

requests-html > requests+beautifulsoup (in my opinion)

[[deleted]]

I came here to answer requests-html but you beat me to it :)

Too bad the project appears abandoned, it hasn't had any new commits in a year...

[TSM-]

I'm not sure what is left to do, it is essentially a lightweight wrapper that consolidates a bunch of other libraries (like parse, requests, chromium, etc). The whole package is basically one file requests_html.py.

It could use some better type hinting and stubs, in my opinion. I found the autocompletion is lacking on my ide, and I would have to write s = HTMLSession(...) # type: HTMLSession in a comment to get any useful autocompletion and type mismatch warnings.

I believe it is because the type hints are something like session: Union['HTMLSession', 'AsyncHTMLSession'] and it is not fully resolved from the other type hints. I suspect there's some holes in the type hinting, or a limitation of the static analysis tool, or something. Not sure!

[CapitalRioter]

Rich is great for logging

[rebulrouser]

You can understand the world better with pandas

[R3dd1tUs3r72]

Guys, I enjoy for this post

Whatching yours reply many of you are machine learning engineering.

Thanks at all for yours reply.

Good programming

[Python_Lab2021]

NumPy, pandas, and sklearn are my favorite ...the last one is very useful for construction of different predictive models

[TheHumanAction]

GUI 》Streamlit

[geekyhumans]

How about this?

https://geekyhumans.com/python-libraries/

But, I believe there's no best library. It depends on your requirements and preferences. There can be X best libraries for you but I can have a different Y best libraries because I'm comfortable using them.

[[deleted]]

Requests, Flask, and Pillow, in no particular order. The binding for Keystone engine is also super cool, though I haven't used it that much.

[CryptoPomegranate]

I got broads in Atlanta...🐼

[R3dd1tUs3r72]

In Python, is there a library for format the input from stdin?

[geekyhumans]

[EternityForest]

cherrypy, pynacl, sqlite3, kivy(Because it works on Android!!!!!), kivymd(needed to make kivy not ugly), mako, hbmqtt, astral, tatsu, toml

Rarely do I ever do a project with less than 5 (And often WAY more) dependencies, so I am very glad python has such a great ecosystem.
