可以的,以下是代码:
```python
i = 1
while i <= 9:
j = 1
while j <= i:
print(f"{j} * {i} = {i*j}", end="\t")
j += 1
print()
i += 1
```
输出结果为:
```
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
```

在python中使用while循环打印九九乘法表
可以使用两个嵌套的while循环来打印九九乘法表,其中外层循环控制行数,内层循环控制列数。具体实现如下:
```
i = 1
while i <= 9:
j = 1
while j <= i:
print('{}*{}={}\t'.format(j, i, i*j), end='')
j += 1
print()
i += 1
```
在上面的代码中,外层循环变量i从1到9,内层循环变量j从1到i,每次输出j*i的结果,并且在每个结果后面加上一个制表符\t,使得输出的结果对齐。同时,在内层循环结束后,需要使用print()函数输出一个空行,以便于下一行的输出。
Python语言 用while循环输出九九乘法口诀表
可以使用两个嵌套的 while 循环来实现九九乘法口诀表的输出。代码如下:
```python
i = 1
while i <= 9:
j = 1
while j <= i:
print(j, "*", i, "=", i * j, end="\t")
j += 1
print("\n")
i += 1
```
运行结果如下:
```
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
