NO Output cant see the Output or error

I have make my code and run it
and it is not giving any errors in the terminal But also I cant check the output in the showcase
How do i know whether i write the correct code or some implementations are still needed

google about status code in python request module and find what is the correct code for succesfull request and try to print the code at the end and see what output you get

what is the correct response code?

google it you will find it.

according to google I am getting right response code but still the post is not showing up on Showcase

Please refer the FAQ: Facebook post not appearing in #showcase channel
Most important part is that you have posted successfully, If You are getting 200 response code.

try to get the response code returned by your code and analyze it whether it is correct or not
