Python Functions, Packing, and Unpacking Packing and Unpacking Unpacking Challenge

whats wrong

def unpacker(val1, val2):
    return val1 + " " + val2

val = unpacker('Python', 'rocks!')

You have set val1 and val2 as parameters in your function, but they haven't been defined outside the function. This will give a NameError when you try to print their values.

The challenge wants you to edit the variable assignment. You don't need to modify the function or the function call. The provided function returns a tuple.

If you have a tuple such as ("Python", "Rocks"), you can use it to assign values to multiple variables at once using the form val1, val2 = ("Python", "Rocks") as long as the number of variables that you are assigning values to is equal to the size of the tuple that you are getting the values from.

If I could give you one word for this code challenge: simplify. You kinda went overboard on this by changing the return value to val1 + " " + val2. You don't need to do that. Everything can basically be kept the same. Go back and look at the video for how the instructor called two variables. It might make a lot more sense then. Hint: val = unpacker('Python', 'rocks!') this is still only calling one variable. How do you call two?
