Dear Experts,  
I was trying to combine 5 or more list with the below logic. Tried Join and Combine Nodes. But unfortunately, was not able to do it. Is there any simple way to achieve this?

edit: thank you I didn’t know how to use the list combine (Thank you M. sovitek )  
edit2: correction to be more concise (this is not mine)

```auto
import sys
OUT = zip(*IN[:])

```
