I do not understand these two lines of codes here, we are putting a list as input and output a random number from 0 to 4. My question is why do we put a list as input if we just want a random number. and this is a board with the size 5x5, but the location of the ship set between 0 and 4，why？

Hey man, the board is a constraint, if you didn’t take the length of your board and returned a random number you could get a number outside of your board which is not in the constraints of the game. (Off the board)

The reason the ship set is between 0 and 4 on a 5x5 board is because computers and most programming languages start counting from 0 to be more efficient. If it was a 6x6 board you would go from 0-5.
0 -> 1
1 -> 2
2 -> 3
3 -> 4
4 -> 5
