Helpers

check_winner

check_winner(game_board)

Check if there is a winner in a given board

Split the game_board for each player and check, using binary operations, if there is a required combination for a win.

Arguments

  • game_board - matrix (7x7), required

Return

  • 1 - id 1 is the winner
  • -1 - id -1 is the winner
  • None - no winner in the giver table

Example

import numpy as np
board = np.zeros((7,7), dtype=int)
board[1,0] = 1
board[2,0] = 1
board[3,0] = 1
board[4,0] = 1
board[3,1] = -1
board[3,2] = -1
board[3,3] = -1

winner = check_winner(board)
if winner:
    print('Winner id:', winner)

bit_board_split

bit_board_split(board)

Split a given board in a bit board for each player

Arguments

  • board - matrix (7x7), required

Return

Return a bit board of 56 of length, one for each player, which represents (in binary) the positions of the player on the board.

next_position

next_position(board, column)

Return the next availabe position in a column

Arguments

  • board - matrix, required
  • column - int, required - Index of the column

Return

Index (row) of availabe position

available_positions

available_positions(board)

Yield all empty positions of a given board

Arguments

  • board - matrix, required

Yield

Index of the column and row of all empty positions in the board

Example

import numpy as np
board = np.zeros((7,7), dtype=int)
board[0,0] = 1
board[1,0] = -1
board[3,0] = 1
board[3,1] = -1
board[6,0] = -1

for x, y in available_positions(board):
    print('Column: {} - Row: {}'.format(x, y))
    print('Position:', board[x,y])

seconds_to_hms

seconds_to_hms(seconds)

Convert seconds in hour, minutes and seconds

Example

h, m, s = seconds_to_hms(5401)
print('Hour: {} Minutes: {} Seconds: {}'.format(h, m, s))
