There's an error saying that the variable hello has not been set. I am not understanding why but I am sure I am not seeing the forest for the trees...
def hello_student(name): hello = "Hello " + name return hello hello_student("Pol")
There is no problem with your code! Merely a misunderstanding of the question. Easy mistake to make!
The question is asking that you store the returned value of the call in a variable named "hello". You currently have a variable named "hello" storing the string to be returned from the method.
You're looking for this at the very end instead!
def hello_student(name): hello = "Hello " + name return hello hello = hello_student("Pol")
