[@ScorpusMugnes]

Hey, Arjan it's been a while now following your design guide videos. But the real problem is that, is it good to place more than one class in a single file, I have been coding in PHP where every class takes it's own file, the code is simple to refactor in that way. What are thoughts?

[@user-fr6ck7fu1q]

The naming of the ICECREAM module is a clever play on the abbreviation "IC", which phonetically mirrors "I See" in English. This choice is fitting for a Python debugging tool, as it elegantly underscores its purpose: to illuminate the inner mechanisms of your code, much like peering through a transparent layer in a typically opaque Python environment.

[@yubeeee]

really nice list, thanks for sharing Arjan! i started using argparse recently in a data engineering context, to set up a main job executor and pass ETL jobs and params as arguments. between that and config libraries like omegaconf and hydra, it's completely changed my application design for the better.

[@alansnyder8448]

A deep dive video on SQLModel would be great. I like it. On my first pass at learning it, the foreign key constraints were a little confusing and I ended up refactoring some code once I fully understood it. But seeing a video might be a great way to know if there is a better way to define them. I was doing a light project with a SQLite-based database, but ultimately want to get to a project that uses PostgreSQL with geocoding. If you did a video like that I would find it very interesting.

[@MedievalChips]

Love to learn about new libraries, you always find something new and exciting. Thank you Arjan!

[@OngakuAikoka]

Your very informative and nicely composed videos helped me get a job in this tough market. Thank you very much, and keep up the good work!

[@Absalatreal]

[@ArjanCodes]

Wow! Thank you so much! I really appreciate it, and I wish you success with your new job! 🎉

[@vman2kay]

Good to see a recommendation for argparse. Most of these modules are already used by me so I'm glad I'm on a similar track. For the question on command line programs, we create command line programs as the work I do is mainly backend and we try to automate as much of our repeatable and tedious processes as we can. Vendor software provides some functionality and our tools just enhance that to make maintenance seamless and fill the gaps not covered by the vendor.

[@DanielRodriguez-lu3uu]

A CLI app is always a good idea when automating boring tasks at work like building reports or extracting data to manipulate. Its quick to develop and fast to execute.

[@arthurelskens8041]

Great video, thanks! Here is a new entry: Ray is a nice framework with a Python API that facilitates code parallelization, whether it is on a single machine or within a designated cluster. Side note for people who might be interested: while Ray offers a user friendly experience, there is a certain degree of syntax overhead, making it challenging to run code in a serial manner without code modifications. To that end, I have build and published a wrapping library (still a work in progress), “ray-ease”, that allows to switch from parallel to serial without requiring code modifications.

[@JR34MZ]

Not a library, but I wanted to mention this: Python Poetry saved me so many headaches at work the past 2 months. I have been been a single dev working on some new infrastructure as code stacks with TerraforCDK and was having a rough time with dependency management. It simplifies virtual envs, dependencies and packaing. Def worth checking it out!

[@mmoreify]

Very useful resource! I would definitely would like a video about Fast API & SQL Model. Thanks for all the great work.

[@ParadiZE3D]

I just found the abseil library for python and so far I really like it. I haven't completely understand all of the build abilities it provides by using bazel, but for building command line Interfaces I like it way more then argparse. You can define arguments as global flags und use or modify them anywhere without having to pass them down accordingly. Found this in a Google Project code and it instantly blew my mind

[@davidmerrell5561]

We write software with command line interfaces all the time in scientific computing. I use argparse very often. Was glad to learn about tqdm, it looks very slick

[@benjaminbertincourt5259]

We add CLI to almost all of our projects for a couple reasons: 1) it's a quick and easy way to test out what is the proper interface/API to your applications before you invest into a more complex API tooling and 2) our applications are mostly pipelines (orchestrated ML lifecycles), not always-up applications. CLI is just a very robust and controllable entrypoint for that type of applications.

[@jace3789]

Which PYPI project is this ?

[@DanHartwigMusic]

I build command line interfaces all the time for data science / ETL utility scripts & processes, pulling data from APIs, roll-up aggregate jobs, interacting with cloud services, etc... argparse, tqdm, and pydantic are all super handy.

[@AndreaDragotta]

Since I've started to learn rust I found the Result type (railway oriented programming) an incredible programming mindset. The basic idea is that many of the exceptions we throw are not really exceptions, but just different paths that our program can take, so we shouldn't treat them differently. If that idea is well integrated into the language, is very powerful and allows to prevent issues.

[@yash1152]

8:45 Result

[@captainwasabi]

exception handling is just a GOTO by another name. Handling errors by result is a much better way.

[@yash1152]

@@captainwasabi zig language for the win.

[@Jackovasaur]

Learning Rust ATM and I chuckled when Result was discussed, especially with the pattern matching. Should definitely be a language feature in the std library

[@isodoublet]

@@captainwasabi So are for loops, so is all of structured programming. Both exceptions and result types have their uses. E.g. operator overloading is utterly unusable without exceptions, might as well not even try. Exceptions are also much more convenient (and performant) when errors happen several nested layers deep. Also, result types are fundamentally unsuited to dynamic languages like python.

[@almquistjohan9318]

I write quite a lot of CLI applications, and personally I find the docopt library really neat.

[@barbaraulitsky8292]

This is super helpful, especially pydantic and icecream. Thank you so much!

Glad it was helpful!

[@nralbers]

One of my go-to libraries for adding 12-factor structured logging to my code is structlog. Works equally well as a replacement or enhancement of the standard logging library, and extremely flexible and extensible.

[@yash1152]

what is 12-factor structured logging?

[@MichaelONeillIrish]

​​@@yash1152pretty sure they just mean "structured logging" (logging all the data in a format like JSON) in a "12 factor app" (which is an architectural pattern for containerized/cloud native applications).

[@yash1152]

hey @@MichaelONeillIrish ! ohkay, thanks a lot :)

[@Jackovasaur]

I've recently started using structlog as a drop in for the std log library, and I can't go back. It has the features of rich + loguru in an easy to use interface!

[@yash1152]

@@Jackovasaur but wount that mean that its not lightweight to run?

[@tapir1073]

nice selection! My favorite library is more-itertools, using it literally in any module

[@brulsmurf]

"I scream" (bad) -> "Ice cream" (nice). Debugging becomes nice.

[@Fritz0id]

I had to use polars for one project due to Pandas being too slow. That project was an exception, and i am typically working on datasets where the speed of Pandas is not an issue. However, I still use polars when I can because I find the syntax so pleasant. I think its going to vary a lot between analysts (most’d rather use SQL than either library) but there’s a chance that for you, its best feature is not its speed but its syntax.

[@Jackovasaur]

Pyspark also has similar syntax to Polars and tbh it's made using pandas a bit frustrating!

[@paulussantosociwidjaja4781]

Thank you, Arjan for the learning - you are so informative. God bless!

[@ArjanCodes]

Glad it was helpful!

[@JorgeEscobarMX]

Great list, I'm really interested in the FastAPI and Model DB combo. I'm a backend developer and I was thinking to learn Flask for that, but this seems better.

[@michaelholland9050]

I use python for command line scripts - -replacing bash scripts. Command line tips are appreciated. Thanks and keep them coming.

[@miyu545]

Love your vids. So much in-depth valuable info. Wish you would create a course from beginner to mastering python though. Get to work! :)

[@quaxBK]

I really like click as an alternative for argparse. Much simpler to use and very powerful! Only downside is that it adds a dependency.

[@solknar7819]

And even better than click: typer (based on click), developed by the same person as FastAPI and SQLModel :)

[@ArjanCodes]

Thanks for the suggestion!

[@TanayPrabhuDesai]

@@ArjanCodes Even better than Argparse and Click is Typer give that a try. Of course it's a layer on top of Click. Typer is made by the same person who made FastAPI.

[@FransjeFranchise]

Click is cool but Typer is also great. Fastapi, SQLModel and Typer are all made by the same author: @tiangolo (Sebastián Ramírez). He's a wizard with leveraging type annotations for a great developer experience!

[@bpetrikovics]

In my experience click makes the code slightly less readable and more confusing. I feel argparse more pythonic.

[@MichaelONeillIrish]

I write CLIs all the time. I generally design everything like a library so it would be easy to attach any frontend to it, but CLIs are easy to crank out with libraries like Typer. At work, I write a lot of custom tooling for things like: managing/requesting TLS certificates, DNS management for customer domains, and other oft-repeated day to day tasks. At home, I wrote an application to automate organizing my media collections (with remote metadata retrieval). I'm usually in the terminal,and automating GUIs is a pain, so I almost exclusively write CLIs for my libraries and leave the GUI or web service frontend for others to implement.

[@teodorlamort3864]

Fire is super convenient for simple CLIs!

[@vitorbuxbaumorlandi6442]

I love Typer! Another great library from tiangolo

[@JohnJohnson-dl8oq]

You, sir, are a new tag in my pinboard. So happy to have found your content, and am looking into your course.

[@ArjanCodes]

Thank you for your kindness, John! Welcome aboard!

[@paulodetarso6252]

Thank you, very useful information for me. I use the terminal almost always, as a Linux user, I create an alias for the software I did and it's enough for me. But I must say I m over 60s and I just study and work with Python for my own fun, also I m very used to 80/90's terminal environment, so it's way better for me than using a laggy GUI.

[@tylernardone3788]

Just discovered tqdm and used it in a recent project. Super simple!

[@dgholstein]

Yes, you betcha I use the command line! Specifically, I have dozens of users who use my Makefiles to git/smbclient/git-select/xmllint/Bamboo configure/setup/deploy our developer environments. The Makefile figures out the host OS and installs OS dependencies using one of yum/apt/yast. It'll also use the pipenv files and specific Python selection to create bash shell launcher scripts. I'm particularly interested in rich-cli which give me a nice interface to either prompt a user for a branch or supply them documentation.

[@diogoje20]

If you're contemplating creating a follow-up video, I highly recommend including a section on the Typed Argument Parser library. I've recently switched to using it instead of argparse, as it offers a more modern and type-safe alternative to Python's argparse library.

[@virolana]

I'd be curious about that too. I have also heard click is great for creating command line apps. I have used it to deal with user prompt inputs and it made a complicated while loop much easier to read and user friendly in just a few lines.

[@HavardSlettvold]

First thing I thought of when I heard argparse was TAP! It's such a simplification over argparse, and also allows scripts meant for CLI to be more easily tested and/or used from code, since you can construct the arguments very easily. I've also seen it used alongside click, but I have less experience with that.

[@GunZFoX]

If you do any calculations that requires units I will always recommend 'units' from 'astropy'. You can basically transform any unit to any unit (like nanometers to feets, if you need that for some reason) in an easy way. Pretty useful in equations where you are not sure if you have converted the units properly as well

[@michaelcorvin1129]

FYI, 'pint' is a neat, standalone alternative to 'units' from the excellent 'astropy'. In a bit of testing I found 'unit' somewhat faster BUT either will add considerable overhead when doing computations using quantities with units. I slightly prefer 'pint' in usage. In any case, I recommend one use quantities for I/O function to validate inputs and to provide quantities with units as output, for doing dimensional analyses and validation through the compute chain during development and testing, but to only pass values from input quantities into production computations and then add units back to the outputs. The cool thing is that the computational chain (if implemented with the right abstractions!) should run either quantities or values without any changes.

[@howardjones543]

Click is a nice alternative to argparse with less up-front configuration. (around 50% of the python code I write is command-line, one way or another, to answer your question - either backend services or actual CLI tools) pydantic's settings classes are really nice for 12factor-style config from environment too, with all the type-checking and validation from Pydantic (e.g. this parameter must be a valid URL or JWT token)

[@filip0112]

5:50 I typically build tools with dynamic menus that can show/hide options depending on circumstances. tqdm is one of libraries to show file transfer. For example I built file manager for my photography work that can automatically batch process newest photos into jpgs, save cropped frames and things like that. As for the logging I use my own function to print and write to file with preset formatting. Sometimes I make CSVs out of this so custom method helps. For me it’s more abaut information gathering than pretty colors in console

[@anthonyhawkes4101]

Awesome libs - if only this popped up for me a few weeks ago, would have been useful for my current project lol.

[@francoisschoeman5350]

Thanks for the informative video... A video on SQLModel would be nice! What about a video about integrating between a REST API and a SOAP API using Zeep (Getting the data from both APIs, manipulating and comparing the data between the two to check if you should make a post, update or delete request to the REST API)? I think it should be interesting... It can probably just be 2 REST APIs as well...

[@whu.9163]

For sure, because SQLModel has not finished docs yet and also it is not clear if this tool is production-ready like fastapi or pydantic

[@j4g094]

I write CLIs mainly to fill gaps in automation. Cronjobs, Deployment or Backup scripts etc. I usually write as a CLI, rather then a simple script. This means more work upfront, but is usually worth it once someone needs to execute it manually for the first time, and someone always will. I usually use click in combination with rich, so thanks for this list of libraries. I will check out argparse for smaller CLIs, since it will reduce the overhead, especially in regards to deploying the app.

[@diegol_116]

Excellent video! I will definitely include some in my stack. I would like you to make a Sqlmodel video, I think it is an interesting option to consider

[@Hacker-at-Large]

I scream, you scream, we all scream for ice cream.

[@yash1152]

2:13 only ur comment makes it obviuos why the name is icecream. its literally a take on "i scream". scream debugging lol.

[@yash1152]

3:04 if not constrained by python version, then these 2 can be accomplished by new f-string syntax: print(f"{foo(123): }")

[@yash1152]

but yeah, still, ic(foo(123)) is still shorter, and (hopefully) supports older python versions too.

[@timoijas7496]

For example in pycharm you can create a live template for shortcutting. For example I made one where if I type log and press tab, it turns into print(f'|=') where the cursor will be at the | symbol. Literally makes the library obsolete reducing dependencies.

[@JamesCairney]

It only makes sense as a name if you've heard the "I scream" rhyme. If you haven't its just a random dairy product.

[@markzuckerbread1865]

Result looks very interesting to me, coming from the functional programming world, I could really use a Result monad!

[@haxwithaxe]

@ArjanCodes - I think that it would be very interesting to learn what you experience in other developers as far as weaknesses go.

[@rantalbott6963]

Thanks, Arjan! This sort of "speed dating" video is usually lame,but you did the extra work of putting in the index and the links, so it's very useful. I would suggest one improvement, though: add a one-line description (just a phrase, like "Does error logging and adds debugging capabilities') to the libraries, because the names often don't give even a tiny clue as to what they're about. You asked about using CLI. I go back to the days of punched cards, and spent a lot of my career doing embedded systems, so CLI is my "native environment". For me, GUIs are what you use to make your CLI results look pretty ;-) When I took my first run at learning Python several years ago, I tried argparse, but found it confusing because it required a fair amount of understanding of Python,especially what you can do with various data types. I'm sure I'd see it differently now, especially if I were writing code for others. But I have decades of experience with getopt, both as a user and a programmer, so I use it in Python, too.

[@maazzi17]

Hi Arjan. This video was really cool 👍 I'm happy I know quite a lot of those libraries 😀 Great you mentioned SQLmodel.

invoke is my go-to for building CLI tools. Hierarchical configs, zero argument parsing (!!), command chaining, self-documenting. Its so simple I build a little CLI for every project as executable documentation for processes, tasks, etc. Can't understand why invoke is not in every Python developer's toolbox. And fabric adds ssh on top so you can run invoke tasks on remote hosts. Maybe if Arjan did a video on invoke and fabric more people could enjoy the awesome.

icecream may be a word play on ICE - In Circuit Emulator, a design tool from the past (nowadays In Circuit Debuggers are the norm, because transparent hardware emulation of a fast chip is hard or impossible) for embedded systems development. ICE's were expensive, a luxury way to develop and debug.

I've been using configargparse which kinda does the same, will check out hydra
