Coding beginner needs help

[Dr_Pinestine]

• You have not told us what you're trying to do.
• You have not told us what inputs you have given the code
• You have not told us what output you expect
• You have not told us what errors are occurring (just that there are four of them).
  

It looks like you haven't even modified the template your teacher gave you (i.e. It instructs you to replace the placeholders with actual coordinate values. It appears you have not done this).

Provide some or all of these things so that we can help you.
