How can I use !expr for inline coding in qarto with python?

Question

In my YAML Header I try this for date:

date: "`!expr format(Sys.time(), '%B %d, %Y')`"
date-format: dddd, D MMM YYYY
lang: de

But if I render I receive an error message:

Invalid Date

Did I use !expr in the correct way?

Answer 1

I found the answer in the Quarto documentation:

date: today

will help in the specific language format.
