Does anyone know any examples of well put together GUIs in Python? I'm mostly a Python hack, and I've got an older wx Python program, and it feels like the presenter (wx.App object) is doing too much work. Like I'll have a separate object that keeps a list of books, and then get_scifi_books() will be defined in the Presenter object. Maybe it doesn't matter because Presenter is the only one using the function, but it feels like I could add in more testing and stuff if get_scifi_books() was defined in a separate object that keeps the books. But then that leaves Presenter mostly empty. How far does that rabbit hole go? If I want to have 3 buttons for get sci-fi, get history, get educational books, should I just have the book object return a list of button names and the associated functions, and the Presenter just blindly puts the list of buttons together?

PySimpleGUI is legit. It’s basically ergonomic wrappers for the built-in Tkinter library. Not sure if it does everything you want, but it has a lot of demos and examples here: https://www.pysimplegui.org/en/latest/cookbook/

I'm guessing you're talking about GUIs without getting into any web dev right? Cause if you're willing to go the web app route, Flask is a pretty great way to use python with some basic bootstrap html and CSS (uses Jinja templates for parametizing html) Outside web dev, I've been curious to try out kivy for this since it claims to have a bit more modern looking UI

I've heard good things about Kivy but haven't tried it. PySmpleGUI sounds right up my alley for a lot of the basic, internal stuff I'm doing. This is all for running local programs so flask may not be the best. I'm a little worried that WxPython may fall seriously behind. It didn't move to python 3 until 3.5 or something, it sounds like not many folks use it, and it just looks like Windows NT. If I want to do fancy guis, is qt more the way to go or should I just not use python?

Qt is probably the best gui framework I've used, its power is pretty limitless and it's in such high demand that there are 2 competing python packages. The biggest advantage of Qt is probably Qt Designer, it's fully interactive and highly robust. It makes a lot of sense to design guis in a gui. Whenever you're happy with the result you can save off a ui file that you load in your code

Yeah I've yet to see any Python based GUI not just look like a slightly more modern version of Visual Basic. Like all the examples in qt designer or tkinter all just scream Microsoft office modal box. I think unfortunately we've all been exposed to too many web based GUIs which have defined the aesthetic and UX expectations in the past decade of "everything-as-a-webapp". Though it's surprising because all that it takes is some thicker/heavier input boxes, minimal gradients/colors/container lines, some highlight responsiveness and heavy padding so that your GUI looks less like this and more like this:  Granted the latter is a React front end but still surprising you need these godawful webpack javascript monstrosity compilers to do anything in the front end but that's the web for you 🤷. The ppl who work on this as their day job all use javascript now so it's the most supported even if it's garbage. Only exception as far as python based that I've seen is a few front end libraries like plotly Dash and streamlit. Granted these are aimed at the data world so I dunno how useful they are for anything more complex than a demo app. If it's just as an internal tool another bit earlier option are Jupyter notebooks with ipywidgets and other ipython based widget libraries. ipyvuetify for example looks great. Google's collaboratory makes the best looking notebooks though they're all cloud based. If you still like working out of an IDE you can get VS Code extensions for them too.

But it's not limited to system themes, you can drop in anything you want (there are tons of cool looking themes in *nix) and make entirely custom things too. Spyder uses Qt, I think it looks pretty good but it's pretty system-y. And then you've got Dropbox, which has a bit of a more modern look

Python code:Python code:e: I think total_degree_credits should also be outside of the for loop, it feels like it's double-counting earlier credit inputs otherwise. Isn't it true that degree_cost should be equal to the sum of all of the term_costs? QuarkJets fucked around with this message at 10:36 on Mar 9, 2023 |

Ah okay that makes sense, though even Windows has moved away from the windows-like GUI and into something more minimalistic and modern. If I was a generalist developer (i.e. not exclusively frontend / GUI) then I could see the appeal since it just inherits the default look and therefore is functional without completely looking like a hacked together Excel VBA form. I imagine with Qt you could do custom theming?

I'm not entirely sure how to phrase this question so my google searching is really missing the mark. I'm wondering if there's some kind of generic Python framework that will allow me to write a declarative statement about how a thing should look, and then gives me some kind of skeleton I can plug in to tell the framework how to make the changes needed. My specific usage is creating group entries in a particular tool. What I'd like is to have some definition of how the groups/folders should look, and then I can tell this "framework" how to read what exists, how to remove something, how to add something, and then I can just say "make it look like this" and the framework will figure out what needs to be deleted and what needs to be added. Basically I'm looking for something like what Terraform or Ansible do (a declarative declaration of what the product should be, rather than an imperative declaration of how to make it) but either it doesn't exist, or I'm searching with the wrong words. "Declarative" isn't a helpful search term, because that has a specific meaning in programming that's different form what I'm looking for. Maybe there's no value in a framework that just helps decide went to create and when to delete, and anyone doing such a thing is better off just writing it all themselves. Or maybe the whole thing is a waste of time trying to make something extremely robust that only gets executed a few hundred times ever.

It's in the instructions that the credits must be stored as a float since later I have to add data validation for a range of 0 - 4.5. I'll take a peek when I get a second and give it a go with your suggestions. Thank you!

Pydantic is more about data validation, not really applicable to the question as I understand it. I'm unaware of any kind of generic declarative framework like that. The suggestion to use deepdiff is, in general, a good one -- I've used it in the past to root out differences in large dict structures and act upon those differences -- but the gap between "I want to declare how I want the world to look" and "now I have dictionaries that I can bounce against each other" is significant if you want to generalize things. If you can't bend one of the existing tools like Ansible to your needs, you're probably going to have to build something. If you're going to build something, think really hard about whether or not you truly need it to be so flexible, especially if it FISHMANPET posted:only gets executed a few hundred times ever.

For book recommendations, Fluent Python is a great point to look at. It really gets you into the nuts and bolts of the language, it was the point where I flipped around from learning Python based on using high level libraries (like pandas) and really understanding the data model from the ground up. It won't teach you a lot about design patterns though.

I'm quite familiar with Pydantic, since this is part of a project using FastAPI, which relies heavily on Pydantic. And that's not what I'm after here. As part of the application (so it can't really be some external tool) I'm managing groups and folders in this tool called Grouper (which is basically only in use at higher-ed institutions and the web API is terrible and there's nothing really in the ecosystem publicly outside the tool itself). For n departments, the application creates a structure in Grouper with about 15 groups spread out across a couple different folders. The groups needed have changed over time. So some departments have, for example, an access group to a service that no longer exists. When the tool creates a new department it doesn't create a group for that unused service, but the existing departments have those groups. And sometimes we might introduce a new service that needs a new group, and so we have to add that group to all the existing departments. So I might define an ideal layout that's something like code:code:

How much Python 2 are y'all living with? What's a sane expectation for carrying along Python 2 applications that don't have any change planned but are expected to keep working forever? If we try and mandate Python 3 by decree but without getting everyone's hearts and minds onboard, there's going to be grumbling for all eternity. My own thoughts on it are that all code does end up being modified at some point, and the less often you encounter Python 2, the more likely you are to make mistakes in it. I'd like to port everything that runs in 2023 to Python 3, full stop. I'm just tired. Tired of having to remember 2/3 differences, tired of collaboration failures where the two parties are on different Python versions and don't voice this at the start of a conversation, tired of ancient packages.

Don't rely on "if it ain't broke don't fix it". Someday some dependency will have a critical vulnerability crop up (or SSL will break or something) and the py2-only library in your requirements.txt will not be updatable and you'll suddenly be on the hook to rewrite the entire thing in an hour. Get out in front of everything before it happens.

How reliable are modern Python-to-exe packages? I recently learned that a research tool I’ve been working on for my job might eventually need to be deployed to outside users, probably closed source. And due to IP reasons on their end, it can’t be a web app hosted on AWS or whatever because their data/results can’t be on a system outside of their company at any time.

One problem with it is that CPython isn't prepared to be statically linked to things. When you package something with pyinstaller, it still uses the system's libraries for lots of things and they need to be compatible. Like on Linux, it won't try to package anything from /usr/lib or /lib. The target system needs a compatible libc It works about as well as anything short of a container
