When we initialize row variable, this visualization explains what happens in the memoryAnd when the board is initialized by multiplying the row, this is what happens inside the memory (each of the elements board[0], board[1] and board[2] is a reference to the same list referred by row)...

In the initialize function, you are given an args variable. args is a Python dictionary. Both keys and values for this Python dictionary are strings. You can find the available keys in the args dictionary along with their description in the table below:...
