I enjoy both managing my Python versions with [pyenv](https://brandonrozek.com/blog/pyenv/) and the literate programming environment [Jupyter lab](https://jupyter.org/). Luckily we can easily manage Python virtual environments via iPython kernels.
We're going to start off with our base Python interpretor
```bash
pyenv install 3.8.4
pyenv shell 3.8.4
```
Then we're going to install the `ipykernel` package.
```bash
pip install --upgrade pip
pip install ipykernel
```
Next we're going to create a virtual environment where JupyterLab will live.
```bash
pyenv virtualenv jupyter
pyenv activate jupyter
pip install jupyterlab
```
With that, we can now create arbitrary environments and add them as a kernel.
