How do you return both the string as well as the parameter value

I get returning a value but not the string as well as the parameter. Seems straightforward but it does not follow from what i have been shown so far

Hi Mark.

You're going to want to concatenate the parameter and the string "Hello" before returning. Here's a possible solution:

def hello_student(name):
    return "Hello " + name

In this example, you pass 'name' as an argument, then concatenate (adding strings together) "Hello " and passed-in value. By doing this, you're creating and returning a single string with the value "Hello [name]". Does this make sense?

Thanks so much. It makes sense although I think with the return keyword it wasn't explicitly stated that you can perform concatenation on a returned value. I take it you can apply any form of mathematical operation on a returned value then? As in return (x/100*2) ^2?

You can use any kind of expression in a "return" statement. It can involve math, call other functions, or some combination of both.
