I don't really understand the question

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 

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

Hey Robert Popescu, you’ve changed the original code a bit. The function returns args. Looking at how tuples can be packed and unpacked:

>>> def unpacker(*args):
...     return args
... 
>>> # given
>>> val = ('Python', 'rocks!')
>>> val
('Python', 'rocks!')
>>> # the tuple can be unpacked as
>>> val1, val2 = val
>>> val1
'Python'
>>> val2
'rocks!'

The same can be done with the returned value from the function call unpacker('Python', 'rocks!'). That is, the result can be assigned to val1, val2

Post back if you need more help. Good luck!!!
