Answer 1

I think as per my analysis you are writing post_detail.py instead of post_detail.html

This is .html file but my mistake you wrote it .py . That's why it will try to find post_datail.html but it will can't able to find this file and throw 404 page not found error

Answer 2

Nethermin it was a stupid mistakes!!

I just make a request on http://127.0.0.1:8000/post/4/ and it's work;

So post/1-3 just dont dont exit.

Sorry for my stupidity
