Variables/Parameters in python query runner

I have a parameter date_range. When I use the same in a python query runner, I get an error.

print({{ date_range.start }})

Error running query: <class ‘SyntaxError’> (“Line 1: SyntaxError: invalid token at statement: ‘print(2022-05-22)’”,)

I have tried using "{{ date_range.start }}" as well, to no avail.
Any help?

Just curious: what’s the purpose of a print statement in this query? Do you see this rendered output somewhere?
