How do I pass a parameter (like metadata or params) into a python cell?

Description

Hi,
I'm looking to pass in a parameter from the quarto document into a python cell.
The utility of this is I'm running 20 reports with different data, and I only need to get the ID of the report that I'm running.
Since I have access to the metadata variables in markdown with {{<>}} I thought there might be a similar syntax or something that I'm missing within the python cell.
However I'm getting a name error whenever I try to reference metadata or params, and checking locals() within the python cell shows no evidence of access to either of these.
I'm on quarto v Quarto 1.6.42
This is a test that's failing to show params.

title: "Test Document"
engine: jupyter
jupyter: python3
format:
html:
code-fold: true
params:
greeting: "Hello from Quarto!"

#| echo: true
#| params: []
print(params["title"])

If you're interested in the context, this is the cell of a notebook that's running the quarto document generation.

`import subprocess

orgs = get_visible_orgs(tree_widget)
for org in orgs:
output_name = f"dash_quarterly_report_{org["title"]}.pdf"
new_title = f"Dash – Quarterly Report - {org["title"]}"
term = 4
subprocess.run([
"quarto", "render", "dash_quarterly_report.qmd",
"--execute",
"--output", output_name,
"--metadata", f"title={new_title}",
"--metadata", f"organisation={org["id"]}",
"--metadata", f"start_date={saved_form_values[0]}",
"--metadata", f"end_date={saved_form_values[1]}",
"--metadata", f"term={saved_form_values[5]}",
"--metadata", f"year={saved_form_values[6]}",
])
print(f"Generated report: {new_title}")`

I realise I've probably missed something, sorry! Any help appreciated.

Could you properly format your post using code blocks for code and terminal outputs? Thanks.
If your code contains code blocks, you need to enclose it using more backticks, i.e., usually four ````.
See https://quarto.org/bug-reports.html#formatting-make-githubs-markdown-work-for-us.

Please read the documentation on parameters: https://quarto.org/docs/computations/parameters.html
