You have the correct structure, but theses fixes needed;

  • it's request.args.get not "arg"
  • the returned string should be "Hello {}". The checker is picky about improvised code
  • remove app.run command. It is not needed and interferes with the checker
  • add missing route to '/<name'

Post back if you need more help. Good luck!!!
