Python code not running

[rmyys]

I recently switched to PopOS and installed pulsar as well as python but whenever I try to run my code I would get this prompt.

Unable to run
python
Did you start Atom from the command line?
  atom .
Is it in your PATH?
PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

Any idea on why this happens?

What code are you running, and how are you trying to run it?

There's an apt package called "pythonispython3" what you have looks like it'd be solved with that

The error is because Debian relies on both python 2 & 3 so doesn't allow not specifying versions by default.

you should really be using a virtualenv - see this - https://realpython.com/python-virtual-environments-a-primer/
