#python

i = 1
while i <= 9:
    j = 1
    while j <= 9:
        m = j * i
        print('{} * {} = {}'.format(j, i, m), end='  ')
        j += 1
    i += 1
    print()
优化后 一：
i = 9
while i > 0:
    j = 1
    while j <= i:
        m = j * i
        print('{} * {} = {}'.format(j, i, m), end='  ')
        j += 1
    i -= 1
    print()
优化后 二:
 i = 1
 while i <= 9:
     j = 1
     while j < i + 1:
         m = i * j
         print('{} * {} = {:d}'.format(j, i, m), end='  ')
         j += 1
     i += 1
     print()
