99 乘法表:
1x99=99
2x99=198
3x99=297
4x99=396
5x99=495
6x99=594
7x99=693
8x99=792
9x99=891
10x99=990
### 回答2:
Python写99乘法表的代码如下:
```python
for i in range(1, 10):
for j in range(1, 10):
print(i, "*", j, "=", i*j, end="\t")
print()
```
解释:
以上代码使用了两层循环,外层循环控制乘法表的行数,内层循环控制乘法表的列数。使用`range(1, 10)`来产生1到9的数字,分别代表乘法表的行数和列数。内层循环打印了每一行乘法表的内容,并使用`\t`作为分隔符使得每个乘法表格对齐。内层循环结束后,使用`print()`换行,输出下一行的乘法表。最终输出的结果即为九九乘法表。
运行以上代码,会得到如下输出:
```
1 * 1 = 1 1 * 2 = 2 1 * 3 = 3 1 * 4 = 4 1 * 5 = 5 1 * 6 = 6 1 * 7 = 7 1 * 8 = 8 1 * 9 = 9
2 * 1 = 2 2 * 2 = 4 2 * 3 = 6 2 * 4 = 8 2 * 5 = 10 2 * 6 = 12 2 * 7 = 14 2 * 8 = 16 2 * 9 = 18
3 * 1 = 3 3 * 2 = 6 3 * 3 = 9 3 * 4 = 12 3 * 5 = 15 3 * 6 = 18 3 * 7 = 21 3 * 8 = 24 3 * 9 = 27
4 * 1 = 4 4 * 2 = 8 4 * 3 = 12 4 * 4 = 16 4 * 5 = 20 4 * 6 = 24 4 * 7 = 28 4 * 8 = 32 4 * 9 = 36
5 * 1 = 5 5 * 2 = 10 5 * 3 = 15 5 * 4 = 20 5 * 5 = 25 5 * 6 = 30 5 * 7 = 35 5 * 8 = 40 5 * 9 = 45
6 * 1 = 6 6 * 2 = 12 6 * 3 = 18 6 * 4 = 24 6 * 5 = 30 6 * 6 = 36 6 * 7 = 42 6 * 8 = 48 6 * 9 = 54
7 * 1 = 7 7 * 2 = 14 7 * 3 = 21 7 * 4 = 28 7 * 5 = 35 7 * 6 = 42 7 * 7 = 49 7 * 8 = 56 7 * 9 = 63
8 * 1 = 8 8 * 2 = 16 8 * 3 = 24 8 * 4 = 32 8 * 5 = 40 8 * 6 = 48 8 * 7 = 56 8 * 8 = 64 8 * 9 = 72
9 * 1 = 9 9 * 2 = 18 9 * 3 = 27 9 * 4 = 36 9 * 5 = 45 9 * 6 = 54 9 * 7 = 63 9 * 8 = 72 9 * 9 = 81
```
### 回答3:
Python写99乘法表非常简单,可以使用两层循环来实现。下面是Python代码示例:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j} * {i} = {i*j}", end=" ")
print()
```
在这个代码中,第一个循环`for i in range(1, 10):`控制行数,从1到9。第二个循环`for j in range(1, i+1):`控制每行中的数字。`print(f"{j} * {i} = {i*j}", end=" ")`用于输出每个乘法表达式,并使用`end=" "`来确保不换行输出。最后通过`print()`来换行。
当我们运行这段代码后,就会输出一个完整的九九乘法表:
```
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
```
这样,我们就成功使用Python写出了一个99乘法表。
