Also star operator yields good results

Sir, do you know where I may find more question like it?

Well, it's true it can be hard to find if you don't know this is called unpacking operator.

Oh, thank you!
I made my trial, but I saw this way for the first time and decided to ask.
Need to use the documentation more often

This is the unpacking operator, you can easily find documentation about this online (like everything about Python). When you see something interesting, or something you don't understand in a code, it's a good idea to copy it and make trials on your computer to see what's happening. You can even do it here, by clicking fork under any solution.

Sir, does operator * replace 'for' cycle? Do I think correctly?

I like this solution!
