I don t understand this for loop

Question

def available_moves(self):
    moves = []
    for (i, spot) in enumerate(self.board):
        if spot == ' ':
            moves.append(i)
    return moves

I am making a python tic tac toe project from a tutorial but I don t understand the for loop I don t get what for (i, spot) means

Answer 1

The following code:

for (i, spot) in enumerate(self.board):

loops through the items in board and given you each items index along with the item.

Specifically, i here refers to the position in the collection of the current element, with spot being the current element from the board collection.

Answer 2

If you do this code you Know what he is each (i, spot) !!

x = enumerate(self.board)

print(list(x))

i = 0, 1, 2... spot = '???'..

(i, spot) = [(0, '???'), (1, '???'), (2, '???')]
