# 入口函数
if __name__ == '__main__':
    for i in range(9):
        for j in range(i + 1):
            print("%d * %d = %d" % (j + 1, i + 1, (i + 1) * (j + 1)), end="  ")
        print()

运行结果：

1 * 1 =  1  
1 * 2 =  2  2 * 2 =  4  
1 * 3 =  3  2 * 3 =  6  3 * 3 =  9

1 * 6 =  6  2 * 6 = 12  3 * 6 = 18  4 * 6 = 24  5 * 6 = 30  6 * 6 = 36  
1 * 7 =  7  2 * 7 = 14  3 * 7 = 21  4 * 7 = 28  5 * 7 = 35  6 * 7 = 42  7 * 7 = 49  
1 * 8 =  8  2 * 8 = 16  3 * 8 = 24  4 * 8 = 32  5 * 8 = 40  6 * 8 = 48  7 * 8 = 56  8 * 8 = 64
