可以使用Python的列表生成式来生成九九乘法表列表并输出。下面是生成九九乘法表列表的代码：

mul_table = [[i*j for j in range(1, 10)] for i in range(1, 10)]

for row in mul_table:
    print(row)

首先，我们使用两个嵌套的列表生成式来创建一个九九乘法表的列表`mul_table`。外层列表生成式的循环变量`i`代表乘法表中的每一行，取值范围为1到9。内层列表生成式的循环变量`j`代表每一行中的每个元素，取值范围也为1到9。在内层生成式中，我们使用`i*j`的表达式来计算乘法表中每个元素的值。

然后，我们使用一个循环来逐行打印生成的九九乘法表列表。对于每一行，我们使用`print(row)`来打印该行的内容。

运行以上代码，即可生成九九乘法表的列表并输出。输出结果如下：

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

以上就是用Python列表生成式生成九九乘法表列表并输出的方法。

### 回答3：
九九乘法表是一个9x9的表格，我们可以用Python的列表生成式来生成这个表格。

代码如下：

mul_table = [[i*j for j in range(1, 10)] for i in range(1, 10)]

这行代码使用了两层列表生成式，外层循环生成1到9的数字，内层循环生成1到9的数字。每个内层循环生成的数字与外层循环生成的数字相乘，得到九九乘法表中每个位置的结果。

我们可以通过以下代码将九九乘法表打印出来：

for row in mul_table:
    print(row)

这段代码遍历九九乘法表列表中的每一行，并打印出来。

运行结果如下：

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

这样，我们就通过Python列表生成式生成了九九乘法表列表，并将其输出。
