AssertionError: ('Hello ', 'Ashley') != 'Hello Ashley'

The question suggests a spelling error? I've read it over a dozen times and I can't find the issue.

creating_functions.py 
def hello_student(name):
    return ('Hello ', name)

When you concatenate in Python a comma automatically adds a space between the strings you are concatenating. However, by using parentheses and a comma you are actually returning a tuple, not a concatenated string. So you can correct it by removing the space in ‘Hello ‘ and the parentheses or you can use the + operator to concatenate the string.

I don't think the comma operator is a concatenation operator in Python. The comma is what makes the tuple, no parentheses required. The rest of your answer is spot-on, though

Michael Hulet, yes, my mistake. Within a print function a comma will behave as I stated in my answer. I’m not sure if it works the same way anywhere else. But you’re right, it’s the comma that makes the tuple, not the parentheses.
