I’m curious about why keyCode doesn’t seem to recognise keypresses when you import processing using an alias. I am using trinket, so that may be an issue.

With this simple code

```auto

from processing import *

def keyPressed():
  print(keyCode)
 
run()

```

I can derive the keyCode value for any key I press. But if I change the import style:

```auto

import processing as p

def keyPressed():
  print(p.keyCode)
  
p.run()

```

the code runs but it prints the word unknown surrounded by less than and greater than signs  
whatever key I press.

Grateful for enlightenment.

Cheers @simonc8 !

The Trinket implementation of Processing + Python is based on Skulpt + ProcessingJS  
And ProcessingJS is kind of a zombie, unfortunately ([GitHub - processing-js/processing-js: A port of the Processing visualization language to JavaScript.](https://github.com/processing-js/processing-js)) so I couldn’t find any documentation about `keyCode`.

Maybe you could try [pyp5js: drawing with Python 3 | pyp5js](https://berinhard.github.io/pyp5js) which is a work in progress, but at least you can open an issue if it doesn’t work…

And there are other options to explore, like [http://p5py.com](http://p5py.com) (Brython based)  
More options at [Python + Processing table](https://abav.lugaralgum.com/Resources-for-teaching-programming/)

Hi thanks for the information.

Do you know if there is a way to use the processing library with Python Idle? If I `import processing` it says ‘No module named processing’ so I suppose it needs installing, but using `pip install processing` doesn’t work. Do I need a different install command?

Processing is a Java library; hence it’s not available via `pip`. You could use [py5](http://py5.ixora.io/) instead (`pip install py5`). Note that you’ll need to have [Java installed](http://py5.ixora.io/content/install.html#install-java) on your computer.

PyScript alpha version was recently released and I’ve converted an online sketch for it: 🐍

> Python is now a full browser client language w/ PyScript: So again I couldn’t resist converting my previous RapydScript sketch “Self Avoiding Walk II” to PyScript. I’ve also added Python type hints to the whole code: All 3 JS Processing flavors run on PyScript just like CoffeeScript & RapydScript previous versions: You can [click here](https://api.glitch.com/project/download/?authorization=3d2d3e71-2277-421f-9d6a-38d0f41b0522&projectId=3dc3a6ae-9818-441a-8f7e-b1d50e7199c3) to download the full sketch so you can edit & run it somewhere else.
