你可以在print语句中使用int()函数将浮点数强制转换为整数，这样就可以去掉小数点了。修改draw_map函数中的print语句，将str(board[i, j])改为str(int(board[i, j]))即可实现：

def draw_map(board, length):
    for i in range(length):
        print('====',end='')
    print('')
    for i in range(length):
        for j in range(length):
            print('| ' + str(int(board[i, j])) + ' ',end='')
        print('')
    for i in range(length):
        print('====',end='')
    print('')

这样就可以打印没有小数点的整数了。
