#I have 4 lists like what's seen above. I want a generator, when I call it will return the count of items at 1st, then 2nd,... index

#so from the above example, I want the following outpout
#>> next(),  4
#>> next(), 4
#>> next(), 4
#>> next(), 1

#so in the case the index of any one of the 4 arrays isn't None, add it to the count
