unpack.py

'''
The asterisk * is the unpacking operator in Python.
- When used before an iterable (like a list, tuple, or generator), it "unpacks" the elements of that iterable.
- Unpacking can be used in multiple contexts:
    + Function arguments: function(*iterable) passes elements of the iterable as separate positional arguments to the function.
    + Creating new iterables: [ *iterable1 , *iterable2 ] creates a new list by combining elements from both.
