You can use a nested list-comprehension to achieve this as follows.
Run the for loop for the 2nd index in a inner list comprehension, and the for loop for the 1st index in the outer list comprehension

board = [ [(j,i) for i in range(5)] for j in range(5)]
print(board)

The output will be

[[(0, 0), (0, 1), (0, 2), (0, 3), (0, 4)], 
[(1, 0), (1, 1), (1, 2), (1, 3), (1, 4)], 
[(2, 0), (2, 1), (2, 2), (2, 3), (2, 4)], 
[(3, 0), (3, 1), (3, 2), (3, 3), (3, 4)], 
[(4, 0), (4, 1), (4, 2), (4, 3), (4, 4)]]
