# OR set the environment variable globally in your shell:
export HERMETIC_PYTHON_VERSION=3.12
```

You may run builds and tests against different versions of Python sequentially
on the same machine by simply switching the value of `HERMETIC_PYTHON_VERSION`
between the runs. All the python-agnostic parts of the build cache from the

But it is way more complex than that.

in-cluster CR is updated and the controller acts upon it to generate a new manifest to apply to the cluster. Note that
both the charts and configuration profiles can come from three different sources: compiled-in, local filesystem.
The source may be selected independently for the charts and profiles. The different steps in creating the manifest are
as follows:

1. The user CR (my_custom.yaml) selects a configuration profile. If no profile is selected, the

### Concurrency and Burgers

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".
