print(i,j[0],j[1],j[2])

Answer 1

It prints the key and then each item inside the list or value of that key.

primary.items() returns a tuple of key-value pair
🔹(key, value).

So for every iteration:
🔹i ---> key
🔹j ---> value

Then it prints the key, the value (first, secon], third indexes), since the value are lists.

For better understanding, here is a snippet with more meaningful variables.
