Return Blank from Python flask API

Question

I have an API that must return just blank and status as 200 OK in case there is no data available

I have tried following things and facing these error

if df.empty:
   return '' , 200

This returns "" in the browser

if df.empty:
   return json.loads('{}'), 200

This return {} in the browser

Send status as 204 (NO CONTENT) makes the previous content to be as it is on the browser

How can i return complete blank with status as 200?

我在彻底探索 Flask 文档后找到了解决方案

from flask import Response
.....
if df.empty:
   return Response(status = 200)
