Can you please tell me what is the cause of that error ?

Question

After raising the ValueError the code should skip that part but why is then it saying "check_right is not defined" ?

Answer 1

its the scoping. if you define anything inside a block it will only be available inside that block

in your code check_right defined inside try block, but being called from the outside

Answer 2
