The short answer: Unpacking refers to the practice of assigning elements of a tuple to multiple variables. You use the * operator to assign elements of an unpacking assignment to assign it a value.
With unpacking, you can swap variables without using a temporary variable. For example:
x = 20
y = 30
print(f'x={x}, y={y}')
x, y = y, x
print(f'x={x}, y={y}')
Output:
x=20, y=30
x=30, y=20
