Hi Blessing Agyei Kyem,

Great article, thank you.

Following your example:

ten_numbers = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) *first_9, last_num = ten_numbers
Enter fullscreen mode Exit fullscreen mode

I tried this:

*first_2, *next_7, last_num = ten_numbers print(first_2) print(next_7) print(last_num)
Enter fullscreen mode Exit fullscreen mode

It does not like it:

SyntaxError: multiple starred expressions in assignment
Enter fullscreen mode Exit fullscreen mode

While this is acceptable:

_, _, *three_to_nine, last_num = ten_numbers print(three_to_nine) print(last_num)
Enter fullscreen mode Exit fullscreen mode 
[3, 4, 5, 6, 7, 8, 9] 10
Enter fullscreen mode Exit fullscreen mode

Take care.

You can't use * twice in your code when unpacking the elements
