用python实现九九乘法表的程序代码

### 回答1：
以下是使用 Python 实现九九乘法表的程序代码：

for i in range(1, 10):
    for j in range(1, i+1):
        print(f'{j} x {i} = {i*j}', end='\t')
    print()

输出结果为：

1 x 1 = 1	
1 x 2 = 2	2 x 2 = 4	
1 x 3 = 3	2 x 3 = 6	3 x 3 = 9	
1 x 4 = 4	2 x 4 = 8	3 x 4 = 12	4 x 4 = 16	
1 x 5 = 5	2 x 5 = 10	3 x 5 = 15	4 x 5 = 20	5 x 5 = 25	
1 x 6 = 6	2 x 6 = 12	3 x 6 = 18	4 x 6 = 24	5 x 6 = 30	6 x 6 = 36	
1 x 7 = 7	2 x 7 = 14	3 x 7 = 21	4 x 7 = 28	5 x 7 = 35	6 x 7 = 42	7 x 7 = 49	
1 x 8 = 8	2 x 8 = 16	3 x 8 = 24	4 x 8 = 32	5 x 8 = 40	6 x 8 = 48	7 x 8 = 56	8 x 8 = 64	
1 x 9 = 9	2 x 9 = 18	3 x 9 = 27	4 x 9 = 36	5 x 9 = 45	6 x 9 = 54	7 x 9 = 63	8 x 9 = 72	9 x 9 = 81	

希望对您有帮助！

要用Python实现九九乘法表，可以按照以下代码编写：

for i in range(1, 10):
    for j in range(1, 10):
        result = i * j
        print(f"{i} x {j} = {result}")
    print()

运行以上代码后，会依次输出九九乘法表的结果，每行乘法式之间用空行分隔开。输出结果如下：

1 x 1 = 1
1 x 2 = 2
1 x 3 = 3
...
1 x 9 = 9

2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
...
2 x 9 = 18

...

9 x 1 = 9
9 x 2 = 18
9 x 3 = 27
...
9 x 9 = 81

这样就成功用Python实现了九九乘法表的程序代码。

下面是使用Python实现九九乘法表的程序代码：

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

运行上述代码，将会输出如下的九九乘法表：

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

以上代码采用两个嵌套循环，外层循环控制行数，内层循环控制每行的输出。外层循环的变量i从1到9，内层循环的变量j从1到i+1。在每个内层循环中，使用`print()`函数输出乘法表的每个表达式，并添加`\t`以制作不同的间隔。使用`end="\t"`使得在每行结束时不会换行，从而使得结果输出在同一行。每行打印结束后，使用`print()`函数进行换行。最终输出的结果就是九九乘法表。
