Not sure why this return value is not being accepted

I have actually gone over this previously but forgotten what the answer is. I seem to be making a " name not defined error. " Do you have to define a argument first before you send it to a function?

creating_functions.py 
def hello_student(title):
    title = "Mark"
    return "Hello {}".format(title)

print(hello_student(name))

You should pass to your function a string name or a declared variable or None like: def hello_student(title): title = "Mark" return "Hello {}".format(title)

name = "Nick" print(hello_student(name)) # Hello Nick print(hello_student("Samer"))# Hello Samer print(hello_student(None))#Hello Mark

Or better yet: make a defualt paramater like: def hello_student(title = "Mark"): return "Hello {}".format(title)
