I just wasted a good half hour trying to figure out why my Python dictionary was in alphabetical order.
I’ve had issues with dictionary order before with 3.5, but that was more or less Python just wanting to put shit in the order IT wants, not alphabetical. And I haven’t had that in months, not since updating to 3.6.
Long story short, VS Code has decided to show me my dictionaries in alphabetical order when I hover over them while stepping code. If I do a print statement, it shows the dictionary in the correct order.
Seriously, you don’t need to do me any favors here.
Oh, the adventures I have with Visual Studio when Python is involved...4
WHY does VS code load up Pandas dataframes so damn slowly? It’s bad enough that it seems to take an extra few seconds to get PyQt5 going, but the dataframes are awful, even with small 50 record Parquet files.
I don’t have the attention span to sit there and wait for this without finding myself playing with my phone or surfing.
I guess for debugging and testing I should just create a column A, column B, column C dataframe on the fly and give it some 1, 2, 3 kind of values.
But, Jesus, man... This shouldn’t take 30 seconds to load a simple form. 🙄2
One of my big gripes about PyQt5 in particular is lack of info, especially on advanced topics. This includes books. I found this on Amazon today:
Qt5 Python GUI Programming Cookbook: Building responsive and powerful cross-platform applications with PyQt https://amazon.com/dp/B079S4Q9T2/...
It was just published in July. I’m thinking I might buy the Kindle book.
On reviewer complained about lack of info on how to handle child dialogs (after fighting with child dialogs that had their own children and dialogs with threading and all that, I feel you, brother). But the 2 reviews it’s gotten look fairly positive.
I wonder how advanced the book gets. Going to read the sample later.4
For chrissakes, the Stackasses on Stack Overflow have, in their typical fashion, downvoted my question instead of attempting to answer it.
I seriously need help with coding a PyQt5 wizard I made in Qt Designer. I’m so sick of fucking around with these idiots.
Can someone point me somewhere PRODUCTIVE where I might get some help? Looking at Experts Exchange and wondering if they have the necessary expertise. Getting to the point where I’m actually thinking of shelling out money. But I’d much rather just find a good online community or something.
I’m developing a fairly sophisticated desktop app in Python with PyQt5 as the widget set. Because my partner insists that all the kids these days love Python.
Piss on Python. And that goes double for PyQt5.
I’m on the absolute hardest section of the app. It’s a fairly complex import of data from PDF reports. There are so many different parts that I decided to go with a wizard.
So, I built a QWizard in Qt Designer. It generates a C++ .ui file, but you just truck it over to the command line and run this pyuic5 command, and it converts to a handy dandy Python class. Woo. You can subclass it and consume it from your Python script.
Sounded SO MUCH EASIER than writing the wizard from scratch. But OH NO. I need to do custom validation on my custom text control at every stage to control when the Next and Finish buttons are enabled, which means I gotta overwrite some damn event.
But I can’t. Because I can’t subclass the individual pages. Because they’re part of the same damn file and the wizard offers no access to them.
I’m almost certain that I’m going to have to completely redesign the wizard so that it’s pages are in separate files, which means I have to recode the bitch as well.
The cherry on top is that there’s zero documentation for this specific thing. None. No QWizard documentation exists for PyQt5 (if there is, they’re doing a damn good job of hiding it), so I have to read the documentation for PyQt4. Not the same animal. Close, but different. Even with the differences aside, this documentation is minimal and useless. “We’re going to tell you in very general terms what you should do, but we’ll give you zero idea how to do it. And we know the very common code method you’ll want to try first won’t work.”
And getting at this stuff when you do it in Qt Designer is WAY different. And all that documentation is in C++. Because apparently you HAVE to speak C++ if you want any real info about PyQt. Because that’s perfectly reasonable, right?
So, now I’ve lowered myself and posted a question on Stack. Because, hey, once you get past the power-tripping, mouth-breathing, basement-dwelling, neck-bearded high school punching bags picking apart your question rather than, I dunno..., BEING HELPFUL, sometimes you can get good info there. Sometimes. They seriously saved my ass at least one time.
But yeah. Fuck Python. Fuck everything Qt.18
