Trying to fix Dell active pen but Python driver won't run

I'm very new to Linux and have absolutely no programming background, so apologies if there's an obvious answer here that I missed.

My computer is an Inspiron 7391 2-in-1. I'm running Ubuntu 20.04.2 LTS.

My Dell active pen isn't registering pressure differences. I tried it in both Krita and MyPaint. I searched and saw that this has been asked before, but the solution I found hasn't worked.

I tried to run the python driver found on this post (Microsoft Pen Protocol support) and it didn't work. I have Python 3.8.5 installed.

I ran this line in my terminal: python3 pen_pressure.py

And this is the return I got:

Traceback (most recent call last):
  File "pen_pressure.py", line 3, in <module>
    import libevdev
ModuleNotFoundError: No module named 'libevdev'

Any help would be greatly appreciated.

You have to install related python3 evdev packages by

sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install python3-libevdev python3-evdev

That fixed that particular problem! Thanks for the help. It's still throwing errors, but at least they're different errors...

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
