i need help on this one guys i am a bit stuck here on this task

Challenge Task 1 of 1 Edit the variable assignment under the provided function so that the tuple returned from the function call is unpacked into 2 variables, val1, val2

unpacking.py 
def unpacker(*args):
    return args

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

Currently, the function unpacker returns a tuple of the arguments provided when running it:

val = ("Python", "rocks!")

The video just before this challenge provides the syntax for assigning each list item to a variable:

val1, val2, val3 = ["a", "b", "c"]

# val1 = "a"
# val2 = "b"
# val3 = "c"

You should atleast make an attempt of solving it before going stright to the community. A good pointer is to move the values to the return statement. It should look like this - return ('Python', ' rocks!'). From there you should look into Steven's suggestion from earlier. Happy coding mate.

perhaps he did try it out before he came here - like I'm doing. Perhaps you should help instead of hindering - happy coding mate

val1, val2 = unpacker('Python', 'rocks!')

This worked and I didn't need to put in the print function

Dont know why, but came with the same solution but it didnt take my code. But if I copy/pasted your the checker works?
