nx-python: Create Python Homebrew for the Switch!

Cyan · May 19, 2018

I didn't try RCM mode yet on my console, but thank you for your reply.
I'm sure someone else will be able to test.

Hey, I see you found the newly added bbcode

AileenLumina · May 19, 2018

Yeah, though I feel they could need some visual adjustments, they look slightly out of place as they don't fit into the site's overall appearance too well (and their bottom margin is quite a bit larger than the top margin). It's not very polished yet, but I like the addition.

nx-python is an ecosystem for developing and running Python homebrew applications on the Nintendo Switch. PyNX serves as the entry point to this ecosystem and allows you to run Python apps on your Switch. It is a homebrew app that contains a port of the CPython interpreter and allows you to run Python applications from the Homebrew Menu. Just name your application main.py and place it next to the PyNX.nro, and it will be executed as soon as you launch PyNX from the Homebrew Menu. Simply grab a release build and copy the content of the ZIP archive into the /switch folder on your SD card. PyNX will appear on the Homebrew Menu. Currently, Python 3.5 is supported. Basic things should work fine, but for many advanced things, like PyGame, you will have to wait a bit until they are supported. This also includes threading, as well as the signal module. Those are high priority, though, so you won't have to wait for them for too long, hopefully. For Switch-specific things, such as button input or filesystem read/write, you can use the nx package that's included in PyNX (see documentation).

I hope nx-python will allow many more people to develop awesome homebrew applications for the Switch.

Wow I just started to learn Python... print:"Awesome"

Any plans for pygame support eventually?

I'm really excited for the gui implementation. I've spent the past couole months learning python and lately my project has been a webbrowser using pyqt. Will it be possible to import that on my own using this? Sorry if this has been answered already

Also thought of this...I mean it is quite infuriating that Nintendo leaves this basic of feature out.

Coming from a noob, would NX-python theoretically run something like a web browser written in python? Attached is something I pulled from user TrebuhD on GitHub. (Cannot post links yet)

Sorry for the long wait. Thanks to elnardu's efforts, we were able to add threading support with v0.5.2-alpha and pyimgui with v0.6.0-alpha. This means that you can now use threading and create GUI-based applications for the Switch in Python. See the pyimgui documentation and this example by elnardu.

Changelog:

Python threads support
zlib support
pyimgui support
urllib works properly now
new PyNX launcher:

Edit: Oh here's the link to the release btw

Would it be possible to run a script in the background while I play a game? Or any homebrew app?

Maq47 · Nov 9, 2018

I want to know something: Is there a way to set the archive flag on a folder on the SD card via PyNX's os.stat function, or is there no Switch equivalent to the 'chflags' command available in PyNX? If it would work, can someone provide a sample script to check the archive flag on "sdmc:/tinfoil/nsp/LHPC_split.nsp/", tell me whether it is, and ask me whether I want to set it if it is not set (and actually set it if I type 'Y', and do nothing if I type 'n', obviously)? I don't know the proper syntax that Python uses (not on any version), but I do know that the 'os' module's 'stat' function can do the job.

Sorry for bumping, but does PyNX support Pygame and OpenGL? I'm learning Python OpenGL and once I've created some 3D games I was hoping to port them over to the Switch and play them with PyNX. Also, can I install other packages, like PyAudio? I'd normally use pip on a computer but IDK how to do it in PyNX.

Is this still alive and working? I'm interested in making some apps using Python since I don't know C (yet)

I guess we might as well consider this project dead...

Developers' time is valuable, if they are not financially supported to maintain their projects. But very few offer the source code and it cannot be improved by third parties, as in this case.

While that can be the case for a lot of projects. I dont think it is what happened here. I think the developer just moved onto something else. Since this repo was uploaded 5 years ago and never touched again(there is no documentation at all except for 1 example.)
If you go through the creators Github you can also see this history repeat with the other repos. With all of the ones made after this python where also created/uploaded and never touched again

Yeah...we can see she gets bored quickly

I was expecting something from an invester to launch. Creating a Game Development Framework for Homebrew is something I wanted to do. But lacking a donation, I change the name and dedicate it to other platforms.

Had it had the impact that other open source engines had, it would have prospered.
