### 回答1:
你可以使用以下代码来编写九九乘法表:for i in range(1, 10):
for j in range(1, i+1):
print('{}x{}={}\t'.format(j, i, i*j), end='')
print()

下面是用Python编写的九九乘法表:
```python
for i in range(1, 10):
for j in range(1, i+1):
result = i * j
print(f"{j} × {i} = {result}", end="\t")
print()
```
运行以上代码,就可以打印出九九乘法表。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
```
每行以`\t`分隔每一个乘法表达式,使用`\n`进行换行。

要用Python编写九九乘法表,可以使用循环语句和字符串格式化来实现。以下是一个使用两层循环的示例代码:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j} * {i} = {i*j}\t", end="")
print()
```
首先,外层循环`for i in range(1, 10)`用于控制乘法表的行数,范围是1到9,代表乘法表的第i行。
然后,内层循环`for j in range(1, i+1)`用于控制每行的列数,范围是1到i+1,代表乘法表的第i行的第j列。
接下来,使用字符串格式化`print(f"{j} * {i} = {i*j}\t", end="")`将每一个乘法表达式输出到控制台,并以制表符`\t`结尾,实现对齐的效果。这里`f"{j} * {i} = {i*j}"`表示将`j`、`i`和`i*j`分别插入到字符串中。
最后,使用`print()`输出一个换行符,使得每行的乘法表达式可以分开显示。
运行这段代码,即可得到输出九九乘法表的结果:
```
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
```
以上就是用Python编写九九乘法表的代码和结果。基于此代码框架,你可以根据自己的需求进行扩展和修改。
