可以使用Python编写程序来打印九九乘法口诀表。代码如下所示:
def print_multiplication_table():
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j} * {i} = {i*j}\t", end="")
print()
print_multiplication_table()
在上述代码中,我们使用了两个嵌套的循环,外层循环控制行数,内层循环控制列数。通过使用格式化字符串f"{j} {i} = {ij}\t"来输出乘法表中的每一项,其中"\t"表示制表符,用于对齐输出。内层循环结束后,通过调用print()函数换行。
运行以上代码,将得到如下输出:
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
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
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
以上输出即为九九乘法口诀表。每一行表示一个乘法公式,每个公式之间用制表符"\t"进行分隔。
