Answer 1

n = input('Standard game? (y/n): ')
if n == 'y':r = 6;c = 7
else:r = int(input('r? (2 - 20): '));c = int(input('c? (2 - 20): '))
if c > 9 or r > 9:
    for i in range(r - 1, -1, -1):
        if i <= 9:print(' ' + str(i) + ' ', end='')
        else:print(str(i) + ' ', end='')
        print(' · ' * c)
    print('   ', end='')
    for j in range(0, c):
        if j <= 9:print(' ' + str(j) + ' ', end='')
        if j > 9:print(str(j) + ' ', end='')
    print('')
if c < 9 and r < 9:
    for i in range(r - 1, -1, -1):
        print(str(i) + ' ', end='')
        print('· ' * c)
    print('  ', end='')
    for j in range(0, c):print(str(j) + ' ', end='')
    print('')
