您可以使用嵌套的for循环来打印99乘法表。以下是一个示例代码:

for i in range(1, 10):
for j in range(1, i+1):
print(f"{j} * {i} = {j*i}", end="\t")
print()

这段代码的思路是,外层的for循环控制行数,内层的for循环控制每一行中的列数。通过在内层循环中打印乘法表达式,就可以得到完整的99乘法表。

输出结果如下:

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
