-====== Python ======
+====== Notes in getting start with Python ======
+Python can be complicated to set up, particularly if using virtual environments.
+===== Virtual environments and choosing a distribution =====
+I used to setup Python via Miniconda in order to have virtual python environments (see [[https://medium.com/@aminasaeed223/a-comprehensive-tutorial-on-miniconda-creating-virtual-environments-and-setting-up-with-vs-code-f98d22fac8e2|this guide here]]. However, I don't like this approach because miniconda seems to be too aggressive in always preferring its own install. For example, the PDE Solver software Firedrake does not like Miniconda/Anaconda.
+Instead, so far I really like the use of [[https://github.com/pyenv/pyenv|pyenv]].
+Setup seems quite simple. On Mac, use homebrew to install via
+<code>
+brew install pyenv
+</code>
+You then need to include some scripts in your startup shell.
+Then install a distribution via
+<code>
+pyenv install 3.12
+</code>
+will install the latest version of Python 3.12. Then you can select this distribution to use as your global one:
+<code>
+pyenv global 3.12
+</code>
