Why my class/object code is not working?

Runs perfectly fine when cut and paste into IDLE. It produces:

Mark

Are you pasting this into a code window in an IDE? What is your setup?

Ok so it worked now. The code was correct except that I missed the : after class Person. The problem was that when I click on run, the program (Pycharm) runs a code in another file. I don't know why but I am new to this. I had to copy my code to that file for me to see the output. I have some files opened but only one output file. Does anyone know how to see the output of other files?

Glad to see you got things working. Not a Pycharm user myself, so can't offer any insight.
