I need help for multidimensional loop

[Growth Hacking Formation]

Hi guys,

I need your help please to sold a complicate problem.

It is difficult for me to find the solution but in fact, I am sure it is just a few lines of code.

The problem is about some kind of multidimensional loop with some test IF.

I worked hours on it, but I am a newbie and it is too difficult.

I was wondering if a super expert in python could give me a hand.

In order to give a maximum of info (explanations + code + screenshot), I prepared a google doc for better understanding. Here in a Facebook post would be too hard to read.

Thanks for help.

Have a great evening.
