The challenge is expecting you to return the string formed by combining 'Hello ' with the value of the parameter name. To combine the strings with string concatenation, you can use + between the strings: 'Hello ' + name. To combine the strings with string interpolation, you could use f'Hello {name}' or 'Hello %s' % name or 'Hello {}'.format(name).

You don't need to call print or assign the value of name to a new variable.

In the line hello_student(hello), hello is treated as a variable, but you haven't defined a value for it, so Python will give you a NameError. To pass the string 'hello' into the function, you would do hello_student('hello'), which should return the string 'Hello hello'.
