Is there any significance of adding '''# airflow''' as the first line in airflow dag. Because python will treat it as a comment.

TLDR; no, there is no significance. I would remove it to avoid any confusion.
I suspect you might have seen this somewhere on the internet, where the topic was around Airflow & DAG processing. Airflow uses a heuristic to discover files that potentially contain DAG objects: it checks if the words "airflow" and "DAG" exist in the file. I suspect adding
"# airflow"might have been a workaround for Airflow to parse that script. However, in normal circumstances this should not be needed: if you have aDAGobject in your script, you will need to importfrom airflow import DAG, which automatically makes Airflow parse that script, so an additional comment"# airflow"is therefore not needed.
