I just downloaded Processing 4.3 and installed Python Mode for Processing 4 from the Contribution Manager. However, when I open up the graphics demos, such as Tentacles, and try to press Run, the demo will not load. The code shows, no error codes are present, the button just flashes white for a second, then stops. I have no problems running similar demos in the Java Mode. I tried a fresh install, to no avail.

[Processing.py](https://github.com/jdf/processing.py) is no longer maintained. Check out [py5](https://py5coding.org/), a spiritual successor to Processing.py that lets you interact with the rest of the Python ecosystem. @hx2A, @villares, and @tabreturn are experts if you have questions!

> Recently I’ve moved my “processing-3.5.4” app folder from a Win 8.1 laptop to another 1 w/ Win 10 and it works the same. However, b/c you also have Processing 4, you’re gonna need to have separate sketchbook folders for both P3 & P4. Here’s a way to do it on Windows: 1st, close all running Processing instances, so they won’t overwrite the “preferences.txt” file we’re gonna edit later. Go to folder %USERPROFILE%\Documents and create a subfolder named code or another name of your liking. …

Thanks, @mcintyre !

Hi, @asterobiology ! If you like, give py5 a try. It is similar to processing.py in that it uses the Processing Jars for much of the graphics functionality. It is actively maintained and fun to use. If you have any questions, let us know!
