Why is this python code not working?Its written correctly and it doesnt show errors so what do I do

Basically the code doesnt show any errors in pycharm so what do I do?

name = input("Hello, What is your username?")

print("Hello" + name + ".")

question = input("Are you dumb? [Y/N] ")
if question.lower() == "n":
    print("So you are smart")
if question.lower() == "y":
    print("oh..okay")
    exit()
