Hi all expert, i have a dataset with about 12 columns having the format shown below.
I am trying to extract 5th numbers from all the columns. for example: ~
[0,3,0,0,0,28,0,0,0,2] --------------------> 28
[0,0,0,0,0,3457,407,605,10,7837] ----> 3457
Anyone has any idea on how to achieve this?

Thank you very much in advance.
