Packing in Python: Grouping Multiple Values into a Single Variable

To pack multiple variables, you need to use the * iterable unpacking operator. Simply place an asterisk * before the variable, and it will pack any number of variables. Packing a variable is only possible within a tuple or a list.

a, b, *c = 1, 2, 3, 4, 5 # a = 1, b= 2, c = [3, 4, 5]
a, *b, c = 1, 2, 3, 4, 5 # a = 1, b = [2, 3, 4], c = 5
a, b, *c = 1, 2 # a = 1, b = 2, c = []
*a, b = 1, 2, 3 # a = [1, 2], b = 3

*a, = 1, 2, 3 # a = [1, 2, 3]
(*a,) = 1, 2, 3 # a = [1, 2, 3]
[*a] = 1, 2, 3 # a = [1, 2, 3]
*a = 1, 2, 3 # SyntaxError: starred assignment target must be in a list or tuple

But the SyntaxError will occur if to use more than one unpacking operator.
