Pytest doesn't *seem* to be using Python version installed with asdf

Cross posted from https://stackoverflow.com/questions/77463416/with-asdf-installed-python-why-does-pytest-use-a-differentpython-version-than-t

I have installed several Python versions using asdf. I am also using Pipenv to manage dependencies. Although I have Python 3.9.4 referenced in my Pipenv file, and asdf reports that I'm using Python 3.9.4, pytest reports that it's using 3.11.6.

For example:

tmoney@tmoney-linux:~/code/wp1$ asdf list python
  3.12.0
  3.7.16
 *3.9.4
tmoney@tmoney-linux:~/code/wp1$ cat .tool-versions 
python 3.9.4
tmoney@tmoney-linux:~/code/wp1$ cat Pipfile
[[source]]

Turns out I have to explicitly set the Python version on pipenv when using asdf:

pipenv --rm
pipenv --python 3.9.4
