      Glad to help! There's so much time to learn during quarantine!
Writing tests for myself because I <3 them so much;
and because they're the missing half of the code.

Like camper_program.py, IPython is a REPL (Read Evaluate Print Loop :)

```bash
$ pip install ipython; ipython
```

```python

%?
%logstart -h
%logstart -o output_from_this.shell.py

GitLab's interface is a bit different:

Here's the *merge request* that added Markdown support to HyperKitty:
https://gitlab.com/mailman/hyperkitty/-/merge_requests/160

# Review the pipeline job log
- Click "Pipelines"
- Click the check mark in the status column (or the build number) of the
first row (the most recent GitLab CI Pipeline)
- Click the "py37-django-3.0" job in the Test column
- Scroll through the job log
  - Find "Creating test database for alias 'default'..."
  - Find "Ran 288 tests in 210.467s"

# Review the merge request (the MR diff)
- Click and hold the browser back arrow (to see history); move the mouse to
the merge request page title; release the mouse
- Click the "Changes" tab
- Click the icon to the left of "Compare"

I could create a Jupyter notebook from this almost- Markdown email.
I could've just created a notebook and saved it as markdown manually (or
automatically with jupytext) and pasted it as this email.

To create a notebook from this:

- Single-click at the beginning of this email, &lt;Shift>Click at the End,
&lt;Ctrl-C> to Copy
- Create new notebook- Select the first cell, press &lt;Esc> (to enter command
mode), then press M (to make a markdown cell)- Press &lt;Enter> (to enter edit
mode)
- &lt;Ctrl-V> to paste- &lt;Ctrl-Shift-Minus> [ &lt;Ctrl-+> ] to split the cell at
the cursor

Jupyter Notebook keyboard shortcuts:
- Open a notebook
- Help > Keyboard Shortcuts

Jupyter Lab keyboard shortcuts:
- &lt;Ctrl-Shift-C> to open the Command Palette
